What is New in SpaceObServer?

Improvements

• SpaceObServer now offers the use of an integrated PostgreSQL database, which replaces the previous SpaceObServer Embedded database. As with its predecessor, this database is ready to use after one click, but offers significantly better performance. The PostgreSQL database also supports the use of the DataCentral service to connect our search tools UltraSearch, the SpaceObServer Web Access and the SpaceObServer Client Access.

• Important note for all users who still have "SpaceObServer Embedded" configured as their database: We strongly recommend switching to the now integrated PostgreSQL database, as it offers significantly better performance with zero administration effort. You can initiate this in the SpaceObServer settings under "Database", your data will be retained if you wish.

• The automatic installer for MS SQL Server Express, which is integrated into SpaceObServer, now installs version 2025 of the free SQL Server Express from Microsoft. This version has increased limits compared to its predecessor.

• Due to internal database optimizations, the search filters in the SpaceObServer interface have been accelerated, especially by file name with path.

• Some adjustments have been made to the configuration interface for the "Automatic Reports" to improve user guidance.

• By optimizing the determination of file system permissions (ACLs), scans in which the scan option "Calculate permissions and save to database" are now performed much faster.

• The operations that update the database following an update scan have been accelerated.

• Errors and access problems when calculating the MD5 checksums are no longer written to the Windows Event Viewer for each file, but bundled for the entire scan.

• Applying filters to file paths on a loaded directory tree, for example via the "Search" menu, could cause the user interface to freeze. This problem has been fixed.

• An issue that caused Data Life Cycle operations to contain unencrypted credentials when copying or moving to Cloud Storages has been fixed. We recommend adjusting the corresponding operations and updating the passwords.

• A problem with memory growth during data lifecycle operations has been fixed.

• A problem with recognizing the correct database driver when connecting to an MS SQL Server under Windows Server 2025 has been fixed.

• Fixed a bug in the "Automatic reports" that caused the export option for exporting "Individual files" to no longer work correctly.

• A problem whereby the status of a scan was not always reset correctly after calculating the MD5 checksums has been fixed.

• Many other minor improvements and corrections have been made.

04/27/2026

Error corrections

• When sending e-mail reports, an error occurred which resulted in an empty e-mail report. This problem has been fixed.

• Automated Reporting: In an e-mail report, other export formats (e.g. PDF) were only included as attachments in the e-mail if an export path for the other exports was also specified in the configuration. This problem has been fixed.

• A problem where the SpaceObServer noted the absence of a password for the certificate when creating a SharePoint scan, although this is only optional, has been fixed.

• The calculation of MD5 checksums during scanning, especially for folders that have many first-level files, is now better parallelized, which in most cases leads to better throughput and performance.

• A bug has been fixed which makes the export of the directory tree faster.

• When using multiple monitors with different DPI settings, there could be problems with too large column headers in the Configure Scans dialog. This problem has been fixed.

03/16/2026

Improvements

• SpaceObServer now checks PostgreSQL database settings and optionally performs optimizations.

Error corrections

• A problem that could lead to missing database indexes during larger scans in PostgreSQL has been fixed.

• Several errors that occurred when using a PostgreSQL database have been fixed.

• When changing export options in the options dialog, visibility and positions of columns previously changed in the details list were reset under certain circumstances. This problem has been fixed.

• Some minor improvements and corrections have been made.

03/05/2026

Error corrections

• A problem where Unicode characters in file and folder names were not recognized correctly when using a PostgreSQL database has been fixed.

• A problem where the settings of the "Distributions" diagram were not saved correctly has been fixed.

• The display of the chart in the "Distributions" tab has been improved, especially for larger amounts of data, by now calculating and displaying bar by bar in the chart.

• A possible unhandled error when opening the options dialog has been fixed.

• A bug where no taskbar icon was displayed in the initial selection of the database type has been fixed.

• Optimizations have been made so that the application more rarely does not respond for a very long time, even when very large amounts of data are processed.

Miscellaneous

• Microsoft SQL Server 2025 is now officially supported.

02/02/2026

Improvements

• PostgreSQL is now supported as a new open source database, as it is now widely used and has good performance and stability.

• On the "Distributions" tab, it is now possible to move, archive or delete all files of the selected distribution (file age or file size) in one step. For this purpose, an option has been added to the corresponding ribbon and the context menu of the selected distribution.

• The determination of duplicate folders takes place parallel to other running scans and is therefore completed earlier.

• When using the central full-text index DataCentral, PostgreSQL is now also supported and thus a non-commercial database for the first time.

• The automatic installer for MS SQL Server Express, which is integrated into SpaceObServer, now installs version 2022 of MS SQL Server.

• When testing the set email configuration via the "Test connection" button under "Options > Export > E-mail", it is now ensured that the set configuration also works correctly for "Automatic reports" via email, which can be executed after a scan.

• When moving large folder structures, the user now has the option of canceling the operation at an early stage during the calculation of the subfolders to be moved. Furthermore, this calculation has been accelerated.

• SpaceObServer now uses the latest MS SQL Server driver for database connections by default and offers to install this driver if no driver is available on the system.

Error corrections

• A problem where the DataCentral service was not installed on Windows 10 systems has been fixed.

• The field for user access in the expert settings can now hold up to 1000 characters.

• With a large number of scans, the program could freeze if a scan was deleted via the "Scan Settings" dialog. This problem has been fixed.

• A bug has been fixed that led to an empty duplicate list in the automatic reports.

• A problem where SpaceObServer could not follow some DFS links has been fixed.

• Changes to access permissions were sometimes not recognized correctly during a new scan. This problem has now been fixed.

• The setting of the maximum number of threads for scans ("Tools > Options > System > Service") was only applied correctly for pending scans after a restart of the scan service. This problem has been fixed.

• The performance of Amazon S3 scans has been significantly improved, especially when a higher number of threads is allowed.

• A problem with increased memory consumption of the scan service has been fixed.

• When exporting the detail list via the OLE interface, in some cases only the column names were exported without content. This error has been fixed.

Other

• As of this version, it will no longer be possible to configure new MySQL or Firebird server databases. We plan to discontinue support for these two database systems in one of the next versions in favor of excellent and well-integrated support for PostgreSQL, as we were able to measure significantly better performance values here.

• Compatibility: Support for MS SQL Server 2012 or older has been discontinued.

• The XML export format for scan results has been removed.

01/14/2026

Error corrections

• During a Windows scan it could happen that the timestamp "Last access" was updated for some subfolders. This problem has been fixed.

• Applying complex filters to a loaded directory tree, for example via the "Search" menu, could cause the user interface to freeze. This issue has been fixed.

• The calculation of the data in the user interface for the "Distributions" view is now calculated asynchronously, which contributes to better usability for long-running queries.

• A problem where expanding the directory tree did not work reliably and exports were incomplete has been fixed.

• An error that occurred when copying or moving folder structures with inaccessible subfolders has been fixed.

• It could happen that the function to cancel a scan in the "Configure Scans" dialog worked with a long delay or not at all. This problem has been fixed.

• Under certain circumstances, the values in the directory tree were not displayed correctly when the "Show size changes in tree" option was activated. This problem has been fixed.

• Using the checkbox function in the Details list caused the program to freeze with a large number of files and folders. This bug has been fixed.

• Duplicate Files: The operation "Check Older Files" (callable via the menu "Duplicate Files > Check" or via the context menu of the list) took a very long time for many entries and could not be canceled. These problems have been fixed.

• A problem where displaying the files of a distribution bar could cause the interface to freeze with large amounts of data has been fixed.

• The display of the list of "Permission changes" took a very long time, especially with a lot of data, and has been significantly accelerated.

• A problem where errors were not displayed correctly during a SharePoint scan has been fixed.

• Double-clicking on a file node in the directory tree led to an error. This problem has been fixed.

• The option "Gray out files that have been deleted since the last scan" could lead to problems in connection with the checkbox function. Elements could no longer be deselected or could not be selected correctly. This problem has been fixed.

• When exporting via the OLE interface, the "ExpandToLevel" function was not taken into account if an explicit export depth had already been defined in the user interface. This problem has been fixed.

• When exporting via the OLE interface, the directory tree was expanded one level too deep when using the "ExpandToLevel" function.

Other

• The display of the comparison tables in the "Duplicate Folders" tab has been improved for dark mode.

• The line spacing of the directory tree and all list elements has been standardized and slightly increased.

• The path to the supplied DataCentral service is now configured with double quotation marks to prevent misinterpretation of the path (thanks to k1xaru for pointing this out).

11/10/2025

• Data Lifecycle Management: In addition to the date types "Date created" and "Last modified", the date of "Last accessed" is now also available as a decision criteria for the data lifecycle operations. Please note that Microsoft deactivates the automatic updating of this date value by default in its current Windows versions. Further information on this can be found in our Knowledgebase.

• For the integration of SpaceObServer data in Microsoft PowerBI, sample files have been created in the installation directory under "Demos\PowerBI\", with instructions for integration have been added.

• The central full text index that SpaceObServer can generate to serve search queries from UltraSearch now supports all common file formats that are also recognized by UltraSearch in a file content search. The search for UltraSearch clients has been accelerated on the server side, especially when a SpaceObServer instance manages many scans and a search for metadata like name or size is performed.

• The performance when creating and updating the full-text index has been improved.

• If there is not enough RAM available during full-text indexing, indexing is aborted earlier to avoid further problems, and a message is displayed.

• The file search by date now allows a more flexible selection by days, weeks, months and years.

• Performance improvements for file operations (copying, moving, deleting, etc.): Especially with many affected files, the dialog now opens faster and the operation is also executed faster.

• The line spacing of list elements has been increased so that the information is easier to read, especially on high-resolution screens.

• When performing scans, more intelligent database timeouts are now used, so that particularly large scans should no longer fail due to database timeouts.

• In the "Scan settings" it is now possible to add a scan directly to a container when adding it, if the container was selected before.

• The MD5 checksums are now also calculated in parallel to other running scans so that the "Duplicate files" and "Duplicate folders" statistics are available earlier.

• When copying or moving files with the "Apply timestamp" option, in some cases not all files were copied due to an error. This problem has been fixed.

• An error in the Data Lifecycle Management options has been fixed where shortcuts were incorrectly created for the moved files during a move operation.

• Despite activating the option "Delete empty folders after operation" in the file operations dialog, it could happen that empty folders remained after a move or delete operation. This error has been fixed.

• In the "Details" list, "0 bytes" was incorrectly displayed in the "Increment" column during the calculation of the actual values. This problem has been fixed.

• A rare problem in the scan service when determining duplicate folders while a scan, that also had this option enabled was running simultaneously, has been fixed.

• The display of content in the "Details" list has been accelerated, especially for very long lists.

• Compatibility: In the previous version 8.3, support for Oracle databases was removed, so that SpaceObServer could no longer be reconnected to an Oracle database via the configuration. As of this version, SpaceObServer no longer accepts Oracle database connections that have already been configured. Support for Oracle as a database system has been completely discontinued with this version.

09/04/2025

Improvements

• The display of detailed information about the full text index is now also available in German.

• The context menu of the directory tree now also offers the file operations available for the scan target such as copy, cut, delete and rename for non-Windows scan targets.

• Unimportant files (e.g. temporary or hidden files) are now excluded during indexing in order to save time and resources.

• The certificate selection for SharePoint scan targets has been made more intuitive.

Error corrections

• A bug where comparing duplicate files always removed a file from the list has been fixed.

• A bug where errors could occur at the end of the scan in the case of a separate scan account has been fixed.

• Despite activating the option "Delete empty folders after operation" in the file operations dialog, it could happen that there were empty folders on the file system after a move or delete operation. This error has been fixed.

• An error where Data Life-Cycle operations were executed based on the creation date, although the creation date is not supported for the file systems (S3, AzureBlob), has been fixed.

• A bug where the right-click menu did not work in the duplicate file list has been fixed.

• The percentage changes in the scan list are no longer set to implausible values when scans are running.

• An error during indexing has been fixed. Now a successful indexing is more likely, even if there is hardly any RAM free on the system.

• An error that caused many warnings regarding the change of identity in the event display of the scan service has been fixed.

• An error that could occur when opening SharePoint scans in the remote client has been fixed by allowing the Azure AD MFA configuration to be managed in the remote client.

• If post scan actions are assigned to containers, all assigned scans now receive the correct target directories of the individual scans.

• Fixed a bug where local scans returned the local path instead of the UNC path from DataCentral.

• Errors when copying and moving files via the clipboard have been fixed.

• Sharepoint URLs of scan targets are now checked for validity when saving.

07/30/2025

• During the installation of the SpaceObServer Remote Client, a dialog for configuring the account for the SpaceObServer scan service was erroneously displayed, which is not part of the SpaceObServer Remote Client. This problem has been fixed.

• Full-text indexing of scan targets has been accelerated by removing an optional step.

• An issue where the scan setting "Consider SharePoint file versions" was not displayed correctly has been fixed.

• When using exclusion filters for a non-Windows scan target in which complete paths should be excluded from scanning, these filters were not correctly taken into account. This issue has been fixed.

• An issue that exporting selected items from the Details list with the "Show details flat" option enabled did not work has been fixed.

• A problem where the exports from the Users or Extensions list was not started correctly due to growth calculations has been fixed. In addition, it is now possible to decide during the export whether the calculation should be completed before the export.

• SharePoint paths that are copied directly from the web browser and pasted into the "Add Scan" dialog are now also correctly recognized as a scan target.

• For containers, the field "Position of scan" in the "Configure Scans" dialog in the "Expert options" tab has been used to display the internal database name of the container and make it editable. This was problematic if the prefix "merged://" was removed from the container. From now on, the "Display name" field is used instead to display only the name of the container and make it editable.

06/30/2025

• A problem that caused an incorrect display after loading checkboxes from the database has been fixed.

• When sending automatic e-mail reports, an error occurred with the activated option "Add date and times to file names". This has been fixed with this version.

• When the option "Show size changes in tree" ("View > Directory tree") was activated, the values in the directory tree were not adjusted when switching the display mode between "Size" and "Allocated space". The same applies to the values of the "Growth" and "% Growth" columns in the "File types" and "Users" lists. Both problems have been fixed.

• The dialog for performing bulk file system operations such as move, copy or delete now opens faster in case a lot of files are affected.

• When scanning with the "Create full text index" scan option enabled, the amount of disk space temporarily required during the scan has been reduced.

• Full-text indexing is now more resilient to corrupt files.

• A problem where deletion via Data Life Cycle operations for Amazon S3 failed has been fixed.

• Fixed an issue where the "Details" list was not updated correctly after moving files.

• Fixed an issue where loading the list of duplicate files could cause the software to freeze under certain circumstances.

• A problem where no comprehensible error messages were displayed in the event of errors in SharePoint authentication has been fixed.

• Other minor improvements have been incorporated into this release.

06/16/2025

New functions

• New central search index: SpaceObServer now has a new service that makes the SpaceObServer database specifically searchable. In addition to the metadata, a full text index can optionally be created for paths scanned by SpaceObServer. Our search tool UltraSearch is the first product that can use this central search index directly - this makes searching for files and content significantly faster, while at the same time reducing the load on the file servers. SpaceObServer thus becomes the central index service in corporate environments.

• The SpaceObServer Standard Edition has a new name: SpaceObServer DataCentral.

Improvements

• The order of the options in the scan settings and in the dialog for adding new scans has been adjusted so that the most relevant are at the top.

• The automatic installer for the Express Edition of Microsoft SQL Server has been improved: The progress is now displayed during the installation and at the end the configuration parameters in the database options are automatically set, and a database is created.

• When exporting the list of duplicate files, the option "Reload per subfolder" was incorrectly not taken into account, so that incorrect content was exported if this option was not activated. This problem has been fixed.

• Various other minor improvements and bug fixes have been incorporated.

05/14/2025

Bugfixes

• An issue where the SpaceObServer Remote Client did not persist the changes to the database connection on restart has been fixed.

• An issue where the database connection for MySQL or MS SQL no longer worked after a restart has been fixed.

• An issue where an error occurred when a scan was added to a container during startup in the embedded database has been fixed.

03/03/2025

New functions

• The calculation of MD5 checksums and the search for similar folders is now also supported for SharePoint scans, SSH scans, Azure Blob Storage and Amazon S3.

• Duplicate search now supports finding duplicates by MD5 checksum across multiple types of scans that are in the same container.

• The functionality of the Standard Edition of SpaceObServer has been adjusted. The limitation of scan targets to only one server has been removed for the Standard Edition. Support for the scan targets Amazon S3 and Azure Blob Storage has been removed in the Standard Edition.

• SpaceObServer now comes with some new PowerShell sample scripts, which you can use for demonstration purposes and as a template for your own SpaceObServer scripts. The new sample scripts can be found in the installation directory in the "Demos" subfolder.

Error corrections

• SpaceObServer can now also retain the timestamps for the creation date and last modification when uploading files to SharePoint. Please note that the extended privilege AllSites.FullControl is required for this.

• When moving files, errors could occur under certain circumstances that the target file could not be found. The cause of these errors has been fixed. The error message itself has also been corrected.

• A problem that caused incorrect results in the calculation of the history diagram and the growth calculations has been fixed.

• An issue where creating indexes on the database prevented new scans from starting has been fixed.

• An incomplete email configuration in SpaceObServer could lead to an unhandled error when sending reports from the user interface. This problem has been fixed.

• Scanning SharePoint with the SharePoint scan setting "Scan all SharePoint Site Collections" did not work. This issue has been fixed.

• The title bar of the application interface now adapts correctly to the accent colors set in Windows.

• Small visual corrections and improvements have been made in dark mode for better recognizability and usability.

02/10/2025

Error corrections

• In some cases, changing the database connection to a new, empty database and then creating a new scan resulted in an unhandled error. This problem has been fixed.

• A problem where an incorrect column was used in a database index has been fixed. This could previously lead to a long running calculation of the history and size increases.

07/16/2024

Bugfixes

• In some cases, the creation date of files was stored incorrectly in the database. This could lead to incorrect values in the Details, History and Distribution diagram. This has been fixed so that future scans are no longer affected. For existing scans, the problem can be fixed with the "Check data consistency" option and a subsequent update scan.

• When displaying size increases in the directory tree, long running calculations could bring the application to a "not responding" state. This has been fixed.

05/31/2024

Bugfixes

• When installing SpaceObServer, an unexpected error message occurred in case the SpaceObServer user interface was still open. This problem has been fixed so that a corresponding message is now displayed in this case, with the option to stop SpaceObServer automatically.

• The integrated, automatic installer for MS SQL Server Express may not have run successfully. This issue has been resolved.

• An issue where the scan service opened too many database connections has been resolved.

• When editing an existing automated report, an additional parameter (/EXPORTEDELEMENTS) was always incorrectly listed under "Command Line > Append these parameters" and added to the parameters. This issue has been fixed.

05/06/2024

Bugfixes

• Under certain circumstances (when users or AD groups occurred multiple times in the permissions of folders or files) it could happen that individual permissions were missing in the details columns “Permissions”, “Own Permissions”, or “Inherited Permissions”. This issue has been resolved.

• The folder sizes displayed in the directory tree when using the "Show Previous Scan Sizes" function ("Tools" menu) may not have been calculated correctly. This problem no longer occurs.

• When selecting the new "Permission changes" tab, there were also short delays for scan targets that do not save permissions in the database (scan option "Calculate Permissions (ACLs) and store in database"). This issue has been resolved.

• In rare cases, an unexpected error could occur when viewing scan settings for certain scan targets in the “Configure Scans” dialog. This problem no longer occurs.

• Under certain circumstances, an unexpected error could occur when closing the "File Search" dialog. This issue has been resolved.

04/09/2024

New functions

• The new "Permission changes" tab provides information about changes that have been made to the access permissions of the selected file system tree. This allows recently made changes to NTFS permissions to be checked and compliance with compliance rules to be ensured. Note: The option to save permissions (ACLs) must be activated in the "Scan settings" in order to create this report.

• Azure Blob Storages can now be monitored with SpaceObServer, as was already possible with Amazon S3 Blob Storages.

• For SharePoint scan targets, you can now choose whether the storage space of file versions is included in the total storage usage of a file. To do this, activate the option "Include SharePoint file versions in storage usage" in the scan settings under Scan options.

Improvements

• The automatic installer for MS SQL Server Express, which is integrated in SpaceObServer, now installs the 2019 version of MS SQL Server.

• Support for the outdated Windows Server 2012 and Windows 8 operating systems has been discontinued.

• SpaceObServer now officially supports MS SQL Server 2022 as a backend database.

• The dialog for creating and revising automatic reports has been improved and elements rearranged to make it more intuitive to use.

• The deletion of old scan data is now only executed when the scan service has no other tasks to perform, so that scans are not slowed down.

• The "Similar folders" statistic has been renamed "Duplicate folders". We have also slightly adjusted the arrangement of the statistics on the right-hand side of the SpaceObServer user interface and optimized the display of the tabs.

• The export of "Duplicate files" has been accelerated by new database indexes.

• In the scan list at the bottom left of the main window, the columns "Growth" and "% Growth" have been changed to "Growth last scan" and "% Growth last scan" and now show the growth between the last and the current scan. Furthermore, the column "Growth last month" has been renamed "Growth last 30 days", as this better describes the content of the displayed values. The calculation of these growth values is now done in advance so that they are now displayed immediately.

Bugfixes

• The automatic e-mail dispatch with generated export files in the attachment has been improved so that the exports are now included in the generated e-mail as real attachments as expected.

• An error with the "Show older scan sizes" function has been fixed.

• Fixed an issue where adding a new scan to a container would display an empty history chart.

• Fixed an issue that caused error messages in the "Duplicate files" list of containers.

• A problem where errors occurred when using MySQL during the calculation of similar folders has been fixed.

• A post-scan action with long paths and many options was saved incorrectly under certain circumstances. This problem has been fixed.

• Many other minor improvements and bug fixes have been made.

03/19/2024

• When scanning file systems with symbolic links and mount points, it could happen that a link was incorrectly not followed. This error has been fixed. Unfortunately, this can cause an endless loop again under certain circumstances when scanning user profiles in the file system. If this happens to you, you can exclude the affected paths from the scan using an exclusion filter in the options.
• The "Overview" selection box in the "View > Show or hide" ribbon could not be used and was always active. This issue has been resolved.
• During the initial scan of a new scan target, the "Scanned Files" value in the "Configure Scans" dialog was not updated correctly. This issue has been resolved.
• If the mode was changed to "Number of Files" in the "View" ribbon, the diagram in the "History" tab may remain incorrectly empty. This bug has been fixed.
• In an automated report with email delivery, the option to completely show the entire directory tree in the report did not work correctly. This issue has been resolved.
• For an automated report via email, the “Exported Elements” settings set under “Options > Export > Email” did not affect the report. This issue has been resolved.
• An issue where an automated email report did not work using the "Use secure SSL connection" option has been resolved.
• In the input field for email recipients, multiple addresses can now be entered again, separated by a semicolon.
• The configuration of the user account in the “Configure Scans > Expert Settings” when using a MySQL database did not work correctly. This issue has been fixed.
• An issue that could cause errors during a scan under MySQL has been resolved.
• Small improvements to the display of the SpaceObServer user interface in dark mode.

09/25/2023

This update contains 3 Community Features from our Feature Voting Platform: Individual names for scan targets, grouping scan targets into "containers" and Dark Mode.

New features

• More options for Data Lifecycle Management: you can now configure which type of file timestamp to use for maximum lifetime comparison. Choose between creation date and last modify date. This also works for existing Data Lifecycle operations.
• Each scan target can now be assigned a display name of your choice. This name will then be used for a scan target in the user interface and in reports, instead of the path. This is convenient for very long paths and provides more meaningful label. (Your request in feature voting).
• The ability to group scan targets into "containers" has been enhanced: containers can now be nested within each other. This allows you to create a hierarchical structure of containers. This is very useful if, for example, you want to structure scan targets correctly on departments including sub-departments. (Your request in Feature Voting)
• SpaceObServer now has a Dark Mode, i.e. a dark theme for the user interface. In the options, the activation can be linked to the Windows color mode or can be switched on and off explicitly. (Your request in Feature Voting).
• With the new "Change Owner" feature, you can now quickly set a new file owner for all selected files. This is very useful if, for example, you have found a group of files with an invalid or inappropriate file owner. The function can be found in the context menu of the "Details" list.
• The demo version of SpaceObServer can now be activated by entering a license key to the full version. This requires an active internet connection. The version available via the customer area can still be installed without an internet connection.
• The user interface is now also available in Polish, Turkish, and Czech. Please note, however, that we do not provide technical support and help files in these languages.

Improvements

• The automatic operations after the scan are now divided into two categories. In "Automatic Reports" you can now find, add and configure all actions that automatically send exports or reports via email after the scan. In "Data Lifecycle" you can configure file operations that are automatically performed after a scan. Both can now be found in the scan settings in the "Post Scan Actions" group.
• The available columns of the "Top Files" have been significantly expanded. This list now has all columns that are available for the "Details" list or all export types. Note: The displayed columns can be easily configured by right-clicking on the column header, or in the options in the "View > Top Files" area.
• In the "Duplicate Files" list, there is now an option in the associated ribbon to check-mark all list entries, uncheck all entries, or even for each duplicate group, checkmark all entries except the newest file.
• File operations: The optional log file has been completely revised. If CSV is selected as the log format, the information is now logged well-structured in separate columns, which simplifies post-processing this data.
• File operations: When using the log or undo script function, the information is now automatically written to an alternative file if access to the specified file is not possible.
• SharePoint Online: The default authentication required for multi-factor can now be set in the SpaceObServer options.
• The component for sending emails has been replaced. With the new component it is possible to support the OAuth2 as authentication method.
• In the lists "Details" and "Top Files", if "Rename" is chosen in the context menu for multiple selected entries, the "Mass Renamer" integrated in SpaceObServer is now used, which offers many flexible possibilities to rename files based on rules.
• Mass renaming gets a new feature: It can be used to convert file and directory names to upper and lower case.
• Mass renaming gets a new feature: Position values can be evaluated from the right. This means that it is now possible, for example, to remove the last x characters from a file name.
• Mass renaming now also supports regular expressions when deleting certain text from file names.
• Other minor improvements have been made.

Bugfixes

• Under certain circumstances, the SpaceObServer scan service terminated with an error message "Duplicates not allowed". This has been fixed.
• The "Check Data Consistency" button in the "Expert Options" under "Scan > Scan Settings" is now working again.
• In the "Scan Settings" it was not possible to set the time of the scan correctly in the "Scan later" operation. This error has been fixed.
• An error in the "Show older scan sizes" function has been fixed.
• An error when editing post-scan actions configured for multiple scan paths was fixed.
• Several other minor bugs were fixed.

04/20/2023

• Bugfix: Under certain circumstances a defined "File Lifetime" operation of a Post Scan Action affected too many files. This issue has been resolved.

09/20/2022

This update contains 2 Community Features from our Feature Voting Platform: Setting a maximum file lifetime and configuration of the maximum number of concurrent scans.

New Features

• New feature for setting a maximum lifetime for certain files: In the “Post Scan actions” you can now also specify that certain files which reached a configurable maximum age are automatically archived, moved or even deleted after a scan.

(Your wish in feature voting)

• The user interface is now also available in Norwegian, Bulgarian, and Vietnamese. However, please note that we do not provide technical support or help files in these languages.
• In the "Extensions" list with activated "Group file types" option, information is now also displayed for file groups in the "Growth" column. This information about the storage growth of file groups was not available in previous versions.
• OLE Automation: With the new function "FileOperation" in the OLE Automation interface of SpaceObServer, you can now automatically move, copy, archive, or delete files. A detailed description of the function can be found in the SpaceObServer help, as well as a helpful sample script in the "Demos" subfolder.
• OLE Automation: With the new filter functions IncludePermissionsPattern and ExcludePermissionsPattern, directories can now be restricted to files and folders for which only certain users have permissions or for which specified users have no permissions. Note: As for all other filters based on permissions, the scan option "Calculate Permissions (ACLs) and store them in database" is also required here.

Improvements

• User interface components have been redesigned for a more modern Windows 11-style look.
• The maximum number of concurrent scans can now be configured in the options under "System > Service > Service Options".

(Your wish in feature voting)

• Implemented some improvements that improve usability, especially for first-time users. For example, the first scan created on an empty database is now automatically loaded into the user interface after creation. We hope this will improve usability, especially for first-time users.

• Fixed an issue that caused incorrect queries on Azure SQL databases.
• Several minor fixes have been included.

08/17/2022

• When editing a Post Scan Action, the options path set for this action was not restored correctly, but the default path was used. This issue has been resolved.
• Fixed a rare issue where the SpaceObServer scan service would shut itself down with an error message "Duplicates not Allowed".
• When creating a scan in the SpaceObServer Remote Client in case the application was not started in elevated mode, there was a problem that the scan was not started automatically. This issue has been resolved.

04/21/2022

This update contains 2 Community Features from our Feature Voting Platform: Concurrent scanning andmulti-factor authentication for SharePoint.

New Features

• It is now possible to scan multiple scan targets concurrently with SpaceObServer. The SpaceObServer scan service now no longer postpones the start of a scan until an ongoing scan of another scan target has been completed. Instead, it processes both scans concurrently. As a result, they are now strictly adhered to and no longer delayed when configured schedules overlap.
• A new dialog for renaming multiple files at once has been introduced and can be found in the "Details" ribbon using the "Bulk Rename" button. Bulk Rename offers a variety of options for renaming existing files using appropriate naming rules.
• The user interface is now also available in Italian and Greek. Please note that we do not provide support or help files in these languages.
• When moving or copying files into a ZIP archive, the destinations SharePoint, Amazon S3 or SSH can now also be selected as the storage location for the ZIP file.

Improvements

• The SharePoint Scan now also supports multi-factor authentication using a certificate file. In our online manual, you can find further detailed information on using this authentication method.
• The icons of the user interface have been revised and ensure a more modern look in Windows 11 style.
• The previously collected scan data is now automatically transferred to the new database when changing the database for the scan data of a specific scan target.
• The "Top 100 Files" statistic has been renamed to "Top Files" and can now be found under the new name in the user interface and help.
• The option "Reload for selected directory" of the "Top Files" list can now also be found in the corresponding options under "Top Files".
• In the "Configure Scans" dialog, the "Show Scan Errors" function in the context menu of the list has been replaced by "Check for Scan Errors". This reduces queries to the database.
• Minor adjustments and improvements in the context menu of the "Details" list have been incorporated.
• Some other minor improvements have been made.

Bugfixes

• The "Show all files of this file extension" function from the context menu of the "Extensions" list accidentally only set the filter to the selected extension. However, did not list all the single files. This issue has been resolved.
• Under certain circumstances, the next scan time of a scan target was not set correctly for scheduled scan, in case the running scan was aborted. This issue has been fixed.
• A "Post Scan Action" that should send a report via email did not work correctly under certain circumstances, if additional statistics were to be included in the email. This issue has been resolved.
• Adding new "Post Scan Actions" for a scan target for which a different database was configured under the "Expert Settings" of the scan configuration did not work properly. This issue has been fixed.
• For scan targets with a very high space usage (3-digit terabyte range) SpaceObServer calculated and reported incorrect and possibly negative percentage values in the statistics and exports. This issue has been resolved.
• Under certain circumstances, the same MD5 checksum was displayed in the "Details" list in the "MD5 Checksum" column for all files of the same scan target. This issue has been fixed.
• An issue where an error occurred when right-clicking on a container in the scan settings has been fixed.
• We have fixed a rare exception when deleting files from the "Duplicates" list that no longer existed.
• OLE Automation: A problem with the "ListExport" method for the "Details" list has been fixed. The export now works as expected again.

Therefore, all customers need new installation keys for V7, which can be found at “Downloads” in the customer area.
• The "Add Scan" dialog now has its own selection box for WebDav scan targets. It is also possible to enter the http notation of a WebDav scan target here, the SpaceObServer then automatically converts this into the UNC notation.
• The lists "Duplicate Files" and "Details" now offers a new master checkbox in the header of the first column. With this checkbox you can check-mark all list entries at once.
• When calculating the MD5 checksums for files, the progress of this operation is now displayed in the "State" field of the scan target.
• The Overview that is displayed below the Ribbon menu now also shows the last scan date of the currently selected scan target.
• In the export options you can now choose whether an "[Files]" element should also be exported for each directory.
• The navigation in the directory structure from within a displayed diagram has been improved. A new button in all diagrams now allows you to switch directly to the higher-level element.
• The "History" diagram and its exports now uses the "Date/Time Format" setting configured in the options, for labeling the X-axis.
• The calculation of the used storage space for very small files, for which the NTFS file system does not actually have to occupy any additional storage space, has been improved so that this value now corresponds to the value reported by Windows Explorer.
• Some improvements in the display on high-resolution monitors for which Windows screen scaling is enabled have been incorporated.
• The dialog for executing file operations has been reasonable revised.
• Some other minor improvements have been made.

Bugfixes

Note: As for all other filters by permissions, the scan option "Calculate Permissions (ACLs) and store in database" is required.
• File operations such as delete, copy or move are now also supported for "Containers".
• The graph of the "Age of Files" statistics now displays detailed tooltips for each interval.

Improvements

• The dialog for adding new scans has been completely revised and now also offers the most important scan options, as well as options for scan scheduling in a clear way. The new dialog is now automatically displayed in case SpaceObServer is started for the first time with an empty database. The dialog is intended to improve the user guidance and usability of the application.
• The columns "Containing Path", "Full Path" and "Allocated" have been added to the list of duplicate files. The "Files" column has been removed. The "Name" column has been adjusted. This column no longer displays the full path for individual files, but only the name of the file similar to the duplicate groups.
• Support for monitors with high DPI values has been improved.
• File system operations, such as deleting files from the "Details" or "Top 100 Files" list are now also considered instantly in the directory tree and other statistics of the SpaceObServer.

To take advantage of this improvement, use a non-proportional font in your email client.

• The visual representation of exported reports in HTML format has been revised. This affects file exports as well as e-mail exports. In addition to these changes, there are now icons for files and folders, and the directory structure is also indicated.
• The hyperlink format defined in the export options is now used in all lists for Excel exports.

Bugfixes

• Bugfix - Exchange Scan: The scan of an Exchange Server could not be executed in the context of a user if the char "?" was contained in the password of the user account. This problem has been fixed.
• Bugfix: When adding many new scan targets (e.g. a complete server with many shares) unexpected errors in the user interface could occur. This problem has been fixed.
• Bugfix: Under certain circumstances a scheduled scan was not started if the expert setting "Observing Server" contained several server names. This problem has been fixed.

09/18/2019

• Bugfix: Under certain conditions errors occurred in update scans, in case the scan option "Calculate Permissions (ACLs) and store in database" ("Scan > Configure Scans > Scan Options") was activated. This issue would have been shown in the "State" field of the corresponding scan. Parts of the data structure might have been stored incorrect in the database. This issue has been fixed.
• Bugfix: It was possible that the scan setting "Use different credentials for scan" ("Scan > Configure Scans > Expert Settings") as well as the monthly update option ("Scan > Configure Scans > Update Options") was not persisted correctly to the database and therefore ignored in scans. These issues have been fixed.
• Bugfix: The option "Limit to this Extension" on the ribbon tab "Extensions" is now also available in case a file type group is selected in the Extensions list.
• Bugfix: The option "Colorize bars" on the ribbon tab "Distributions" will now be memorized and restored after an application restart.
• Bugfix: The small size indicator bars shown in the background of each folder in the directory tree now visualize the correct percentage values for root folders grouped in a container.

• Bugfix: When using exclude filter for a scan ("Scan > Configure Scans > Scan Filter") with multiple filters applied to full paths, not all of the filters used where applied correctly. This issue has been fixed.
• Bugfix: Modifications on the “File Groups” ("Tools > Options > View > File Groups") used for the "Extensions" statistic had not been persisted after a restart of SpaceObServer. This issue has been fixed.
• Bugfix: When expanding 1st level folders in a "Container" the size of the expanded folder was reset to zero when the included roots were located in a different database ("Scan > Configure Scans > Expert Settings > Database"). This issue has been fixed.
• Bugfix: The "Details" list might show fewer files after using "Delete" from the context menu of this list. This issue has been fixed.
• Bugfix: Using the "SpaceObServerCmdLineParser" for exporting the "Duplicate Files" now again exports the Duplicate groups including single files, as was the case in former versions.
• Added support for text-only export of the "History", "Age of Files", and "Size of Files" statistics.
• A few minor bug fixes and improvements have been incorporated.

10/17/2017

• Bug fix: Adding a complete server to the SpaceObServer database might result in strange errors ("Out of Memory") or even unhandled errors.
• Bug fix: When using exclude filter for a scan ("Scan > Configure Scans > Scan Filter") and all filters applied to full paths, the scan did no longer see any files.

• A few minor bug fixes and improvements have been incorporated.

08/31/2017

New Bitness:

• Native 64 Bit: SpaceObServer is now available as a native 64 Bit application. This applies to the user interface as well as the scan service (SpaceObServer Agent).

New Filter:

• SpaceObServer can now store access permissions (ACL) of files and folders in the database. This enables users to easily create filter criteria (e.g. user name, permission type, owned or inherited permissions) and use them on a scanned folder structure.

User Interface:

• Ribbon User Interface: The new ribbon-style user interface of SpaceObServer is more than just a cosmetic measure: Easy navigation and feature selection secure user-friendliness.
• A new preview pane has been added to the right side of the "Details" tab. This pane shows a summary of the most important information of the selected file in the Details list, as well as a preview of the file content (in case this is supported/available for this type of file).
• The performance when loading scans in the SpaceObServer user interface has been optimized, especially for very large scans.
• We adjusted the names of some columns in the "Details" list, to match their corresponding columns in the Windows Explorer.
• The "File Search" panel of SpaceObServer has been revised. The available filters are now grouped in a more logical and structured way.
• Many more improvements implemented in the user interface enhance the look and feel and match modern Windows operating system styles.

Charts:

• The "Tree Map" chart can now optionally show single files, file extensions, or extension groups inside the chart.

Database:

• If you do not have a real SQL server database to use with SpaceObServer, the software no longer uses an MS Access desktop database as default. The new database type "SpaceObServer Embedded" is a customized Firebird database, which shows much better performance than MS Access and supports concurrent usage of the database.
• We do now store timestamps like "last modified" and "creation date" of files and folders in UTC (Universal Time Coordinated) format in the database. This ensures data consistency across time zones and multiple machines. Please note: This might cause a longer run duration for the first update scan of existing scans.
• Official support for MS SQL Azure has been added.
• Please note: Support for IBM DB2 Database has been dropped.

Scan Engine:

• We optimized the performance of update scans by using less complex update statements in the database. This applies especially to very large scan structures and to scans with many modifications on the scanned directory tree.
• Thanks to early dissolving of network dependencies, the performance of SpaceObServer's local shares scans has been increased.

New Export Options:

• The PDF and printed exports have been completely revised. This also applies to the printer preview pane. These exports do now look more like TreeSize Professional and can now include the various charts that SpaceObServer offers. The PDF and printed export can include single files now.
• The Excel export can now include charts (as known from the HTML export). Charts are included in separate sheets in the exported Excel file.
• The HTML, Excel, Email, PDF, and the printed export can include the various list statistics (Top 100 files, Extensions, Users, Details, and Duplicate Files) that SpaceObServer supplies.
• The new configuration section for the PDF export now enables users to configure the PDF documents. In former versions, the PDF export used the same settings as the printed report.

Exchange Server Scans:

• Exchange Server scans can now optionally break down scanned mailboxes into organization units (OUs).
• Email subjects are now by default shown in the "Name" column of the Details list and all exports. You can activate the new option "Anonymous email subjects" for Exchange scans to hide email subjects.
• Thanks to the optimized usage of the internally used paging, Exchange Server scans now run faster.
• Please note: Support for Exchange Server 2003 scans has been dropped.

OLE Automation:

• The existing OLE Export functions have been enhanced to optionally include additional lists and charts when exporting to HTML, Excel, Email, or PDF.
• Human-readable strings for each "Information Type" which can be used in functions instead of integer values have been introduced.
• The new function "UpdateAnnotation" to set the "Annotation" field of files and folders has been included.

Changed Compatibilities:

• Support for Windows XP and Windows Server 2003 has been dropped.
• SpaceObServer v6 (Enterprise und Standard Edition) will be offered in 64 Bit only. If you require a 32 Bit version of SpaceObServer, please send us an inquiry.
• Support for MS SQL Azure has been added.
• Support for IBM DB2 Database has been dropped.
• Support for Exchange Server 2003 scans has been dropped.
• .Net Framework: 4.5 required.

Miscellaneous:

• When using "Tools > Show previous scan sizes" SpaceObServer now also lists files which are already deleted, but existed in the previous scan.
• Introduced function "Hide folders smaller than X MB" to exclude small directories from the directory tree.
• The functionality "Load XML reports" to show former saved XML reports has been removed.
• The "Full Path" column of the "Details" list and all exports now always end with a trailing path delimiter for directories. The shown/exported information is now similar to TreeSize Professional.
• The "Optical media size" has been removed from the available values to be shown directly in the directory tree.
• The "Wasted Space" column has been removed from the Details and all exports.
• Bug fix: The exclude filter of a scan did not match if the used pattern ended with a white space. This has been corrected.
• Several minor improvements and fixes have been incorporated.

08/11/2017

• Bug fix: An exception occurring when loading a "Container" while "Top 100 Files" was active has been fixed.
• Bug fix: Fixed an error which occurred when deleting a folder from the directory tree while the pie or bar chart was shown.
• Bug fix: Size changes were not calculated for all folders when exporting the directory tree with size growth column included.
• Bug fix: Using the OLE Automation function "ExcelReport" with a file name including the variables "%DATE%" or "%TIME%" did not work correctly.
• Bug fix: Sometimes size values shown in the directory tree were cut when the option "Show Size changes in tree" was activated.

11/11/2015

New Statistics:

• Introduced a new "Similar Folder" statistic. It provides an overview of identical directory trees (trees, which have the same content and structure) or nearly identical directory trees, which have nearly the same content and/or structure. These statistics enable you to identify similar or duplicate folder structures which are e.g. created by copying.
  • You can activate the generation of the new "Similar Folder" statistic in the "Configure Scans" dialog for existing or new scans.
  • Please note that activating this statistic will generate more workload on the SpaceObServer scan service ("SpaceObServer Agent") and more space allocated in the SpaceObServer database.

Charting:

• All pie, bar and line charts provided by SpaceObServer have been completely redesigned. They have been replaced with MS Chart from the .Net framework. Therefore, SpaceObServer now requires the .Net framework 4.0 or higher to be installed on the system on which it is executed. The SpaceObServer installer will download and install the .Net framework 4.0 if it is not installed on the system.
• You can now activate interpolation for line series shown in the "History" chart, to get a smoother size development curve.
• The "History" and "Distribution" chart can now be exported in a textual format (Text or CSV file).

Faster User Interface:

• The SpaceObServer user interface loads faster now. This is especially noticeable when a large number of scans is stored in a database.
• SpaceObServer now uses internal caching mechanisms when building "History" graphs or calculating "Size Growth" information. This improves the speed of the user interface when working with these values.

New Export Options:

• The exports of SpaceObServer have been improved and are now nearly identical to TreeSize Professional.
• The HTML export has been revised: Enabling JavaScript generates a dynamic view which allows expanding and collapsing each level of the folder structure. Subfolders are now properly indented. Folders are formatted as hyperlinks; clicking on them will open the folder.
• You can now choose whether an Excel export of the directory tree will have expandable / collapsible levels ("Tools > Options > Export > Excel > Formatting").
• If the number of exported elements exceeds the number of rows an Excel sheet supports, the export is now continued on a new sheet.
• The author is now set in exported XLSX files.

New Options dialogue:

• The options dialog has been completely redesigned to provide a clearer and more intuitive user experience.
• Each export type now has its own configuration page. This simplifies the configuration of export settings.
• A dedicated export type for CSV files has been introduced. CVS exports are now available in the main menu ("File > Export > Save to CSV file") and the context menu of the directory tree (sub menu "Export").
• All export formats can be configured to export the same columns as the "Details" list. This is the default value for new installations.
• The settings for exported HTML files and HTML emails can now be configured independently.
• You can now configure which charts will be exported along with a HTML export and which charts will be sent as email attachments.
• The separator used for exports to CSV files can be configured.
• The appearance of date time values can now be configured more precisely (date only, date with time, time with or without seconds).

Exchange Server Scans:

• Archives in mailboxes and public folders can now be scanned.
• Mailbox addresses will be fetched from multiple Active Directories in trusted domains and forests of the current machine.
• Existing email aliases were scanned redundantly in the past. Now, only one mailbox (primary email address) will be scanned. The owner of mailboxes and public folders will be retrieved from the Active Directory.

OLE Automation:

• Added the procedure "ExcelReport" which exports various lists and charts to an Excel file.
• Added the procedure "ReloadAllRoots" which forces the refreshing of all roots.
• Introduced the function "GetIDByPath" which queries the identifier (ID) of a directory for a given path.
• Added the function "GetFolderInformationByPath" which queries the directory information for a given path.
• Added the optional parameter "Charts" to procedure "HTMLExport" which enables the user to export charts along with the HTML report.
• The procedures "ChartExport" and "ChartExportEx" now support the export of users statistics and extensions statistics as pie chart or bar chart.
• The order of the parameters "Height" and "Width" of the function "ChartExportEx" has been changed. The function call is now ChatExportEx(ExportPath, ChartType, Width, Height).
• Changed behavior of the parameter "ObservingServer" in function "AddRootToDatabase": "localhost" can be passed in order to use the executing machine. Leave the parameter value empty ("") if any available server shall execute scans for the selected directory.
• The procedure "SetRootProperty" now supports the new parameters "ScanUser" and "ScanPassword". Via these properties the user can set the user name or password of the scan credentials of a root in the database.
• The function "GetRootProperty" now supports "LastError". If the last scan was not successful this function returns the related error code. Otherwise the function returns 0.

Miscellaneous:

• MS SQL Server 2014 is now officially supported.
• The name of the columns "Last Change" and "Last Access" have been adjusted to "Last Modified" and "Last Accessed". This applies to the lists "Details", "Top 100 Files", and "Duplicate Files" as well as all export types.
• Several minor improvements and fixes have been incorporated.

10/22/2015

• SpaceObServer now provides more meaningful "owner" information for mailboxes and emails of an Exchange Server 2007 and higher.
• OLE Automation: A new optional parameter "UserAcess" has been added to the function "AddRootToDatabase", enabling you to configure a list of users and/or groups which are allowed to see and access the scans and the scanned directory structure.
• Bug fix: The duration of the initial scan was unusually high when using a MS SQL Server database.
• Bug fix: A double click on a file in the "Top 100 Files" list led to an unhandled exception.
• Bug fix: Adding a new scan for Exchange Server 2003 ("Scan > Configure Scans > Add Scan > Exchange > Exchange Server 2003") led to an unhandled exception.
• Bug fix: Update scans on a MS SQL Server database using compatibility mode 80 (MS SQL Server 2000) led to errors in the Windows event log and the SpaceObServer Agent was stopped.
• Bug fix: Update scans were not executed correctly in case the option "Purge data older than 0 days" ("Scan > Configure Scans > Scan Options") was used in combination with a different "Database" for scan data ("Scan > Configure Scans > Expert Settings").

07/15/2014

Reporting & Exports:

• A new menu entry "Send by email" in the "File" menu enables you to send scan reports instantly via email. The email settings can be configured via "Tools > Options > Email". Additionally, an "Email" button is now available on the toolbar of each tab ("History", "Charts", "Details" etc.). It can be used to send the tab's content via email.
• A new column "Cost" hast been introduced to the "Details" list and all available export types. It can be used to easily calculate costs for occupied server space and e.g. break them down to department level. Please note: You can configure the used value and unit to calculate the cost for each scanned share or drive in the configure scans dialog ("Scan > Configure Scans > Scan Options > Cost").
• You can now configure a list of users and/or groups which are allowed to see and access the scans and the scanned directory structure in the SpaceObServer user interface ("Scan > Configure Scans > Expert Settings > User Access"). SpaceObServer will hide the scans (i.e. not show them in the user interface) from all other users.
• The columns "Quota Limit" and "Quota Usage" have been added to the "Users" list. They offer a quick overview about the usage and limit of the built-in Windows quota features from within SpaceObServer.
• The treemap chart now shows the size value configured in the "View" menu in addition to the folder names.
• The size value "Wasted Space" in the "View" menu has been replaced by "Optical Media". Additionally, the bar chart no longer shows the wasted space in an extra bar when "Allocated space" is activated.
• The new column "Hardlinks" has been added to the "Duplicate Files" list.
• The columns "Full Path" and "Path" in Excel exports of the "Details", "Top 100 Files", and "Duplicate Files" list now contain hyperlinks.
• Hyperlinks for single files in the Excel export now point directly to the single file (previously they pointed to the parent directory).

Database:

• Optimizations in the database maintenance lead to faster update scans for shares and drives with an extensive scan history.
• The check states of files and folders can now be saved to the database to restore them at a later date or in another SpaceObServer Remote Client.

Navigation:

• New forward and back navigation buttons for the directory tree have been added to the "Scan" toolbar ("View > Toolbars > Scan").

File Search:

• You can now easily define a filter for all files owned by an unknown or no longer existing user account ("Search/Filter > Configure > Owner/Attributes > File Owners > Check invalid file owners").

Move Checked Files:

• The function "Move Checked Files" is now always available. When using this function, the option "Show Checkboxes" will automatically be enabled.
• Checking of large folders in the directory tree or the details list no longer results in a blocked user interface.
• If no files or folders are checked via checkbox, the checkboxes of the currently selected files and folders will be enabled automatically.

OLE Automation:

• The new function "EmailExport" enabling users to send the scanned directory tree, lists, or charts via email has been added.
• The new function "AddContainer" has been added.
• The function "AddRootToDatabase" now accepts Exchange and SSH scans. Additionally, a new optional parameter "Container" has been added to this function, enabling you to assign a scan directly to a new or existing container.

Configure Scans:

• It is now possible to add scans to a container or to move them to another container via the context menu.
• When changing the database of a container in the "Expert Settings", you can now tell SpaceObServer to use the selected database for all included scans.
• Containers will no longer automatically be expanded or collapsed when moving or adding scans in the "Configure Scans" dialog. Additionally, these settings are now stored when the dialog is closed.

Installer:

• You can now pass the database connection string to use via the command line (/CONNECTIONSTRING) when executing the installation file of SpaceObServer.

Miscellaneous:

• You can now select multiple files at once in the "Top 100 files". Please Note: Context menu operations (e.g. "Delete") are applied to all selected files in a list. Additional export operations (e.g. "Save to File") of a list will export only selected files as long as more than one file is selected in the list.
• Scans already included in a container can now be moved to other containers via the context menu of the directory tree.
• A context menu for the SpaceObServer scan service icon in the status bar has been implemented. You can start, stop, pause, and continue the service via this menu.
• The context menu entries "Move Checked Duplicates" and "Deduplicate Checked Files" in the "Duplicate Files" have been moved to the context submenu "SpaceObServer".
• The "Last Access" and "Owner" columns on the "Duplicate Files" tab are now deactivated by default.
• Bug fix: Under certain conditions the "SpaceObServer Agent" caused an increase of the number of handles and the memory consumption of the "lsass.exe" process. This is no longer the case.
• Several minor improvements and fixes have been incorporated.

06/11/2014

• Bug fix: Fixed an error that could occur when replacing duplicate files by hardlinks, via the "Deduplicate" function.

09/03/2012

• The "Age of Files" statistic on the "Distributions" tab now uses the current date (without time) as reference value. This ensures consistent statistics within the same day.
• Placing checkmarks on directories containing a large number of files is much faster now. Activate the option "View > Show Checkboxes" to provide checkboxes in the directory tree and the "Details" list.
• Bug fix: An export of the directory tree to an Excel file ("File > Export > Save to Excel File") with file extension ".xls" (format before Excel 2007) led to an error message loop, if more than 65,535 rows were exported.
• Bug fix: Fixed an error that occurred on the first start of SpaceObServer when using MS SQL Server 2000 as backend database.
• A few minor bug fixes and improvements have been incorporated.

08/20/2012

• MS SQL Server 2012 is now supported.
• You can now add scans for all shares of a complete server at once. Enter the server name with two leading backslashes (e.g. "\Server1") in the edit field above the directory tree, or use the "Add Scan..." function of the "Configure Scans" dialog. All shares will be grouped in one container.
• The Exchange Server scanhas been enhanced. The scan is more stable and much faster now.
  • Please note: This is a breaking change, so unfortunately your "History" data of previous Exchange Server scans will be lost. We apologize for any inconvenience caused.
• The performance of update scans, especially for scans of large data storages, has been increased: the post processing mechanisms have been optimized.
• Move Checked Files: It is now possible to burn the checked files to an optical media.
• The Deduplication feature of the "Duplicate Files" list now has an enhanced dialog: It shows the number of all checked duplicate files and the disk space that will be recovered. You may specify a log file that logs all performed operations in detail. Furthermore you may configure in detail how to handle duplicates that are not located on the same volume: Since hardlinks cannot be used you can choose to use symbolic links or to simply leave them as they are.
• The new columns "Inherited Permissions", "Own Permissions" and "SHA256 Checksum" are now available in the "Details" list and for all types of exports.
• If "Number of Files" is the chosen view type ("View" menu) and the option "Show size changes in tree" ("History" tab) is activated, the directory tree now shows the changes in the number of files.
• Move Checked Files:
  • It is now possible to copy all checked files to a different location instead of moving them.
  • Introduced new option "Include directory with drive letter to avoid name collisions". Activate this option to avoid name collisions when moving files from several drives.
• You can now rename containers within the context menu of the "Configure Scans" dialog ("Rename Container...").
• You can now configure the scan options (e.g. "Follow Links Mountpoints and External Symbolic Links", "Track NTFS Alternate Data Streams and NTFS Hardlinks",...) for all included scans in a selected container at once in the "Configure Scans" dialog.
• OLE Automation interface:
  • You can now assign container names to the property "RootDirectory".
  • With the new methode "AddRootToDatabase" it is now possibility to add new roots with extended settings (e.g. NTFS Change Journals, calculate MD5 checksums,...).
  • The "List of Scans" shown below the directory tree can now be exported using the function "ListExport".
• Additional note: SpaceObServer V5.1 has been successfully tested on Windows Server 2012 RC, using ReFS.
• Several minor improvements and fixes have been incorporated.

07/20/2012

• Bug fix: The export of a scan from MS SQL Server to Firebird ("Scans > Configure Scans > context menu > Export > Export to SQL Server") now works as expected.
• Bug fix: Occasionally, the field "Size Growth" in the "Users" and "Extensions" list stuck in the state "calculating...".
• Bug fix: If you right click in the directory tree an exception occurred in case the list "Users" or "Extensions" was activated and at least one entry was selected in the list.
• OLE Automation: The filter "MinFolderSize" can now be assigned to a value greater than 127. Also a former set "SizeUnit" is now taken into account (Previously the value was always taken as MB).

02/28/2011

• Bug fix: When using SpaceObServer with a MS SQL Server 2005 database scans did not run successfully.

02/17/2011

• SpaceObServer is now available in two different editions: The Enterprise Edition includes all the known and new features. The lower-priced Standard Edition only scans one server and includes the functions relevant for this application range (without SSH and Exchange Server scans, no OLE Automation interface).
• Scans can now be grouped in so-called "Containers" to generate merged statistics like "Duplicate Files", "Extensions" or "History" for several scanned shares. Containers can be added and configured using the context menu of the directory tree or in the "Configure Scans" dialog using drag & drop operations.
• SpaceObServer is now able to scan and archive the storage of Exchange server mailboxes (only "Enterprise Edition").
• Firebird can now be used as a backend database for SpaceObServer.
• By optimizing the build up and update process of the backend database, the performance of the scans has been increased, especially for the initial scans (increase of 20 - 30%). Please note that scans newly added by SpaceObServer V5 cannot be used with SpaceObServer V4.x!
• The "Extensions" list can now be grouped by file types like "Audio Files", "Video Files", "Office Files", etc. This feature can be turned on or off by a new toolbar button. The file groups can be configured on the new tab "File Groups" in the Options dialog ("Tools > Options").
• The scan scheduler ("Scan > Configure Scans > Update Options") has been enhanced so that you can now also schedule monthly or weekly scans (e.g.: on the 1st, 15th and 30th of every month or every week on Monday and Friday).
• Scans can now use any user credentials instead of the login of the scan service "SpaceObServer Agent" to scan network or local shares. The user name and password can be entered on the new tab "Expert Settings" of the Configure Scans dialog. In this new tab you can also configure some enhanced options which were formerly only accessible from within the context menu of the list above.
• All lists can now be saved in HTML and RTF format by choosing the appropriate format in the "Save" dialog.
• You can now deduplicate checked files in the "Duplicate Files" list by using the new context menu entry "Deduplicate Checked Files" or the new button in the duplicates toolbar. The deduplication replaces existing files with links to reduce the allocated disk space.
• Now the "Number of Files" is shown in the "History" graph if this view type is chosen in the "View" menu.
• The new options "Preserve directory structure" and "Automatically rename existing files" have been added to the "Move Checked Files" dialog ("Tools > Move Checked Files").
• The size unit TB (Terabyte) has been added to the "View" menu.
• The information types "MD5 Checksum" and "Path Length" are now available in the "Details" list as additional column and for all types of export.
• Improved the look of the user interface when using large system fonts.
• In the Configure Scan dialog ("Scan > Configure Scans") you can now choose "Purge Data older than 0 Day(s)" in the "Scan Options" to execute only initial scans for the selected share. Note: In some cases executing only initial scans will be more efficient than updating existing data in the database. In this case there will be no "History" or size growth information available for these shares.
• The new function "Copy as Text" has been added to the context menu of the "History" chart. This function enables you to export the values of the history chart as text to the clipboard.
• The "List of Scans" beneath the directory tree can now be exported as a text file by using the new context menu entry "Save List...".
• The printed tree report now also uses the colors shown in the directory tree if the option "Use bold Text and Colors for Printed Reports too" ("Tools > Options > View") is activated.
• File Search: The attribute "encrypted" has been added to the file attribute include/exclude list (tab "Owner / Attributes").
• Modifications of the scan configuration ("Scan > Configure Scans") of any scan are now no longer applied immediately, but by clicking the new "Apply Settings" button.
• You can now use environment variables like "%APPDATA%" in the "Scan Path" edit field (above the directory tree).
• If any entries in the "Duplicate Files" list are check-marked, the sum of all checked files is now shown in the status bar, as it is already done in the "Details" list.
• Introduced a context menu with functions to (un-) check all entries in the list of visible export columns ("Tools > Options > Columns / Export").
• The shortcut for copying the selected entries of the Details list to the clipboard is now "Shift+Ctrl+C". "Ctrl+C" in the Details list now copies the selected files or folders to the clipboard, just like the Windows Explorer.
• When changing the sort type of SpaceObServer ("Sort" menu) the position of top level directories are now no longer changed in the directory tree.
• The support for Windows 2000 has been dropped because Microsoft dropped it in July 2010. SpaceObServer V4.3.2, which is compatible with Windows 2000, remains available in our customer area for registered customers with valid maintenance.
• Bug fix: A selected "[Deleted]" node in the directory tree (these nodes are shown if "Show Size Changes in Tree" is activated) caused incorrect size growth series shown in the "History" chart.
• Bug fix: The update scan now correctly regards if any directory within a Ascan has been replaced by a symbolic link with the same name.
• Bug fix: When deleting a file or folder from the "Details" list that no longer exists, the file was not removed persistently from the "Details". This could lead to inconsistent sizes in the directory tree and the Details list.
• Several minor improvements have been incorporated.
