What is New in TreeSize?

New Path Entry in File Search

You can now find, select, and manage search targets much faster and, if desired, entirely using the keyboard.

• You can now add new search paths in fewer steps, and the entry process can be controlled entirely via the keyboard.

• The path selection drop-down menu now displays all drives connected in Windows Explorer, in addition to favorites and recently searched paths. Local drives, network drives, cloud services, and others appear with their drive letters and available storage space.

• In the dialog for selecting scan and search targets, you can select multiple drives just as you would in Windows Explorer and add them all at once.

• In the new search history, you can see all recently searched paths and your favorites at a glance. You can clear the history entirely or entry by entry.

• You can permanently pin particularly important search targets using the pin icon so they’re always at your fingertips. You can pin multiple selected paths at once with a single click.

• Selected search destinations appear as individual tiles in the path bar. The remove button is located directly on the tile and is much easier to click.

• A left-click now selects a search path instead of immediately switching to edit mode. Use Ctrl+click and Shift+click to select multiple paths and remove them together using Delete or Backspace. To edit, simply click a second time or press F2.

• Unaccessible drives and paths are marked as such even before the search begins. This helps you avoid searches that yield no results.

New Selection Logic for Results Lists

In the duplicate search, it’s crucial to select the right files. With the new selection logic, you can use rules to specify which duplicates are selected. This feature is also available in the standard file search.

• The selection dialog has been completely redesigned. Frequently used selections are easily accessible and clearly grouped.

• You can specifically select only the files located in a certain path, or only those not located there. For example, you can keep all files in your archive folder and select only the copies located elsewhere.

• For more complex requirements, you can build a comprehensive set of rules using the advanced selection options to create your own custom selection.

Additional New Features & Improvements

• Our chatbot, JAMie, is now available directly within TreeSize and answers your questions about the application without requiring you to leave the program. JAMie cannot see your screen and has no access to your scan data, for example.

• The file preview now appears only when a file is selected. This leaves more space in the right-hand pane.

• You can now display two file previews simultaneously to compare contents directly. Enable this feature using the new pin icon in the file preview or the corresponding checkbox in the ribbons.

• You can now change the file owner recursively for all subelements of a folder in a single step.

• You can now configure the level of detail for SQLite exports just as you do for other exports. For example, you can create exports without information about individual files, making them smaller and more efficient.

• The TreeSize setup now features a new, modern design.

• We have thoroughly revised the help entry on the various scan targets; it is now much easier to understand.

Bug Fixes

• Special characters are now displayed correctly again when importing an SQLite scan.

• Umlauts and special characters (e.g., ä, ö, ü, ß) are now displayed correctly again in Excel exports (.xlsx) on systems with the Windows option “Beta: Use Unicode UTF-8 worldwide” enabled.

• An error that could occur when searching for file contents in Google Drive has been fixed.

• The installation now runs smoothly again, especially for update installations. In some cases, a background process had been interfering with the installation.

New, flexible deduplication options (hardlinks, symlinks, shortcuts) give you full control, while smart color highlighting and tooltips ensure an intuitive experience.

• Duplicate search results can now also be filtered by column after the search.

• Installation is now also possible if the user does not have admin rights on the machine on which the installation is being carried out. As with a Windows Store app, the application is installed in the user profile. Users with admin rights are asked during the initial installation whether they want to perform an installation for all users or continue without admin rights.

• The duplicate search has been expanded to include filter options. If possible and useful, completion options are displayed.

• The deduplication log now shows the link type used during replacement (hard link, symlink, shortcut).

• A bug that could cause a crash when selecting multiple items in the Top 100 file list has been fixed.

• In the file search, an error occurred when searching for permissions with a user name in the format DOMAIN\User (with backslash), which aborted the search. Domain-qualified user names are now processed correctly. Users who previously received an error dialog when using permission filters with domain user names can now perform such searches without any problems.

• After a search for unique files with a large number of results (e.g. ~100,000 files), expanding and collapsing the result group could cause the application to freeze. This problem has been fixed.

• A possible freezing of the application when reading synchronized cloud paths (e.g. OneDrive) has been fixed. The query has been optimized so that slow or unresponsive Windows shell extensions are largely bypassed when evaluating in the background.

• Repeated right-clicking on folders during a scan could lead to increasing slowdowns and even freezes. This has been fixed.

• When moving files and folders in SharePoint Online, the version history and metadata of the moved items are now retained and are not updated by the file operation.

• An error that could occur when sending the search result by email if the search was not completed has been fixed.

• UI scaling for high-DPI Windows settings has been improved for the file search module.

• An error that caused an endless loop of authentication attempts when entering an incorrect certificate path has been fixed.

• The input of the search target in the file search has been fundamentally revised for easier handling. Paths can now also be added directly by clicking in the search target line.

• TreeSize now makes it possible to display the occupied storage space of S3 objects including all existing file versions, provided the option "Include SharePoint or S3 file versions in the calculation of the 'Occupied space' value" is activated. If this option is not activated, only the size of the latest version is displayed as before.

• For a more focused workflow, the filters in the duplicate search are now hidden by default and better labeled.

• The option "Ignore NTFS hardlinks" of the duplicate search is now activated by default so that already deduplicated files are not displayed again even after restarting the application.

• In the file search, the filter for "Permissions" is now displayed at the first level of the search filter selection. This makes it easier to access the function.

• TreeSize can now optionally 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 this error has been fixed. The error message itself has also been corrected.

01/30/2025

New functions

• TreeSize now supports scanning and analyzing Amazon S3-compatible object storage solutions such as Wasabi, Dell EMC ECS, Digital Ocean Spaces or Minio.

• File search: A new search template "Directories with own permissions" has been added. This can be used to find directories for which the inheritance is interrupted because they add their own permissions. In combination with a minimum directory depth, directories can be found in which inheritance is unexpectedly interrupted.

• File search: The behavior of the option to skip offline files has been revised. In future, TreeSize will only skip offline files for the content search and the determination of checksums. The option has been renamed accordingly. This will continue to prevent unwanted downloading of offline files. At the same time, offline files are now included in the search result in a normal search that does not require the file to be downloaded.

• With the test version, only 500 files could previously be deleted, moved or copied at once in the file search. This limitation has been removed.

• Improvements have been made to the user-friendliness of the dialog for starting a new scan.

• When opening a file from SharePoint, for example by double-clicking, the containing folder is no longer opened in the browser, but the file directly.

Error corrections

• When scanning user profiles in the file system, an endless loop could occur under certain circumstances. This bug has been fixed.

• An export of the list of top files was not complete under certain circumstances. This bug has been fixed.

• It is now also possible to start scans via drag & drop into the empty area of the directory tree, even if drag & drop file operations are disabled in the options (e.g. in simple application mode).

• An unexpected entry was created in the start menu when the application was started. This entry is no longer created.

• A problem with resolving link targets for nested links on DFS systems has been fixed.

• The error handling when searching for duplicates within ZIP files has been improved.

• The error handling when sending emails has been improved. A message dialog with information about incomplete settings is now displayed.

• If files were moved via the file operations dialog with the option to create shortcuts at the original location, an incorrect file name for deleting the shortcuts was stored in some cases if the "Undo script" was activated. This problem has been fixed.

• In rare cases, the installation could freeze when registering the context menu entries for TreeSize. If the registration fails, the installation will now be continued and completed anyway.

• An error in the duplicate search on SharePoint has been fixed, which could prevent duplicates from being deleted as expected.

• Help in the outdated Windows CHM format is no longer supported and delivered. Instead, TreeSize now installs and uses help in the more modern HTML format. The help is also still available as a PDF.

• The installation via the publicly accessible installer can now also be activated offline, i.e. without Internet access. The additional version previously available in our customer area (TreeSize-x64-Full.exe) is therefore no longer required.

• Support for the outdated Windows Server 2012 R2 and Windows 8.1 operating systems has been discontinued.

09/25/2024

Error corrections

• When trying to scan an Outlook mailbox with a 32-bit version of Outlook, an unhandled error occurred. Instead, a message is now displayed stating that only the 64-bit version of Microsoft Outlook is supported.

• File Search: Search filters for the "Media > Length" column now interpret the value entered by the user in seconds. Previously, the unit 100ns was used, as it is stored internally by the file system.

06/04/2024

Error corrections

• The drive list now fills the items asynchronously. This handles possible application freezes that might have occurred with slow or unreachable network resources.

• A few dependencies on third-party components with known but low-rated vulnerabilities have been updated.
  The help files in CHM format continue to reference an older version of jQuery, as the CHM-format does not support a newer version. If necessary, you can simply delete the CHM files. TreeSize will then automatically open the online help instead.
  The Redemption64.dll library currently still refers to an older version of ZLib. We are in contact with the provider of this component to update this dependency as well. The library is only required for scanning Outlook mailboxes.

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

• File Search: Simple Search now allows you to use parentheses in your search term to refine your search. For example, entering (readme, license) *.txt will find all text files with "readme" or "license" in the name.
• File Search: In Simple Search, spaces now act as AND links between search terms, not as part of the term. The search term "New Folder" now finds folders named "New Folder" as well as "Folder New" or "New Test Folder". Use quotation marks for exact matches. A comma now works as an OR operator; it is sufficient if one of the terms occurs in the name.
• You can now start mass renaming directly from the Explorer context menu for selected files in Windows 11.
• Via the jumplist entries in the Windows taskbar (the jumplist appears after right-clicking an application icon), various areas of TreeSize can now be opened directly, e.g. the most recently performed searches or scans.
• File Search: File operations can now be performed directly on files inside zip files.
• The details list now supports two additional columns, which can be activated via "More Columns" in the right-click menu of the header: 1. "Total Items": shows the sum of subfolders and files in total and recursively, 2. "Number of Subelements": shows the number of files and subfolders a folder contains directly. (Your request in feature voting)

Improvements

• TreeSize can now also use the user currently logged in to Windows to log in to SharePoint (integrated Windows authentication).
• File search: The user interface for creating and editing search filters has been further improved. For combined filters, it is now even clearer which filters belong together and how they are linked. Individual filters can now also be adjusted or deleted directly via an overlay menu.
• File search: The "Empty folders" filter template has been improved.
• The TreeSize Duplicate Search is now available in the Windows File Explorer context menu. (Your request in feature voting)
• Information required for an export is now increasingly determined asynchronously to speed up the export. (Your request in feature voting)
• General memory usage reduced: TreeSize now discards unnecessary scan information early during automated exports, significantly lowering memory consumption for exports. Using /PrefetchFiles False, asynchronous preloading can be disabled, further reducing memory requirements but increasing export duration.
• TreeSize now also supports large folders in SharePoint libraries that contain more than 5,000 items.
• Azure Blob Storages can now be accessed directly via the URL displayed in the web browser.
• File search: The error messages for failed deduplications have been improved.
• File search: Search paths that are not checked are now retained when switching between searches and are no longer removed for the current session.

• A possible error when comparing a scan with a scan previously saved to a file has been fixed.
• Empty directories are now also copied in the "Copy/Move" operation.
• If elements cause problems during the copy/move operation in the file search, this is now logged correctly. A misbehavior could occur in previous versions when copying files from a mobile phone.
• The option to calculate date values for folders based solely on the files they contain now works again as expected.
• The context menu options are no longer written to the local registry when running the portable version of TreeSize Professional.
• The scan history may have been saved in the profile of the current user (AppData) when using the portable version of TreeSize Professional. In this situation, the history is now always stored together with the other options in the folder of the portable installation.
• When deleting a symbolic link to a folder, the symbolic link is now deleted and no longer the linked folder and its contents.
• File search: The command line parameter /SCAN is now also evaluated correctly in combination with /FILTER regardless of the order of the parameters.
• When comparing a scan with a previously saved scan, folders that had been deleted in the meantime were no longer displayed as such. This error has been fixed.

01/18/2024

• Under certain circumstances, an unhandled error could occur when accessing the Tools tab or opening the About dialog. This error has been fixed.
• In addition, in the demo version, this error could cause the application to assume the Personal edition, even though the Professional edition was selected during installation. This error has been fixed as well.
• The "Last saved by" column now provides correct values again for files on SharePoint.
• Other minor corrections and improvements have been made.

08/24/2023

• The export from TreeSize is now much faster if it contains the individual files as well as the folders.
• TreeSize now also supports the upload of large files (>250MB) to SharePoint.
• An unhandled error when scanning Outlook mailboxes has been fixed.
• 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.

This update contains 3 Community Features from our Feature Voting Platform: Scanning Outlook mailboxes, scanning Azure Blob Storage and more!

Main Module / General

• TreeSize now supports the scanning and searching of mailboxes that are included in a locally installed Outlook. This includes IMAP as well as Exchange and Exchange-Online mailboxes. (Your request in feature voting)
• SQLite was added as a new export format for scans. As an alternative and successor of the XML export, this format offers the possibility to export, import and compare scans on a single file level. Thus, a comparison of different scans down to file level is now possible.
• TreeSize supports Scanning and browsing of Azure Blob Storage. (Your request in feature voting)
• The demo version of TreeSize can now be activated by entering a license key and then becomes a full version. This requires an internet connection. The version available in our customers area can still be installed without an internet connection.
• The component for sending emails has been replaced. With the help of the new component, OAuth2.0 authentication is now supported.
• The application mode (Simple, Normal, Expert) can now be configured via the administrative templates as well. That way large organizations can preconfigure a mode for the users when rolling out TreeSize.
• In the directory tree the Enter key opens not only files but also folders in the configured file manager, usually in Windows Explorer.
• The user interface is now also available in Turkish and Slovak.

File Search

• By means of a new comparison method for the duplicate search, files with "similar names" or identical name stem can now also be found. This comparison method recognizes file names as similar whose naming indicates multiple versions, such as: "Presentation Department V1.ppt", "Presentation Department V2.ppt"
• The context menu for copying to the clipboard has been extended by additional options: the containing folder path and the file name can now also be copied. (Your request in feature voting)
• The search performance for certain search filter combinations has been significantly improved. For example, a search that uses a long list of "owners" as filter now takes only a fraction of the original time.
• The "Permissions" filter now also supports searching for files without "effective access rights". This means that a user has no access permission for the specified operation. This can be the case either because there is an explicit entry "Deny access" or because there is no matching "Allow permission" entry.
• The user interface has been revised. The navigation elements on the left side now make it even clearer which of the stored search definitions are currently active.
• The TreeSize file search now stores the search paths per search instead of globally for all searches. This increases flexibility by allowing you to store different combinations of search parameters and search paths. Based on feedback from our users, we believe this change will be useful for most users. If this is not the case for you, we would be very happy to hear about your use case.
• The dropdown for selecting search paths now allows you to pin individual paths explicitly. This way, frequently used paths will stay there, even if they are not selected as search paths.

Bugfixes

• An error when deleting files in the “Top Files” list during a running scan has been fixed.
• When scanning user profiles in the file system, an infinite loop could occur under certain circumstances. This error has been fixed.
• A bug that prevented renaming rules of the new case-sensitive type from being edited has been fixed.
• A bug that could cause files, that were previously renamed, to be renamed again under certain conditions has been fixed.
• An error when creating new folders with special characters on SharePoint has been fixed.
• An error when uploading files with the special characters % or # in their names to SharePoint has been fixed.
• A problem in the display of compared scans was fixed. Deleted folders are now displayed as such again.
• An error in editing scheduled tasks configured for multiple scan paths has been fixed.
• Multiple addresses separated by a semicolon can now be specified in the input field for e-mail recipients again.
• The new function for adjusting the case in the mass renaming dialog is now correctly applied to the selected part of the file name.
• An error when comparing two saved scans of all SharePoint SiteCollections has been fixed.
• Several other minor fixes and improvements have been made.

05/30/2023

• The preview on the right side of the details list could no longer be switched on correctly in some cases. This error has been fixed.
• An error during the installation of the software certificate has been fixed. This could lead to a certificate error message in rare cases.
• An error when comparing a scan that is still running with a saved scan was fixed.
• Numerous other minor fixes and improvements have been made.

02/09/2023

Main Module / General

• You can now select scan targets other than the Windows file system (e.g. SharePoint, Amazon S3, SSH, etc.) for comparison under "Scan > Compare with Path". The (size) differences are then displayed. This can be handy, for example, after migrating a directory system to check it for changes.
• When updating a folder or scan that has been compared with another folder or scan, the comparison folder is now also updated.
• You can now find TreeSize on top level in the new context menu of Windows 11.
• The log file that can be activated in the file operations dialog has been completely revised. If CSV is selected as logging format, the information is now logged in well-structured in separate columns.
• The new command line parameter /ShowAuthGui can now be used to force login dialogs to be displayed, even if TreeSize itself was started without a user interface.
• When exporting the pie chart of file types, an empty chart could be exported under certain circumstances. This error has been fixed.

Mass Renaming

• The mass renaming dialog has been extended by a function to convert file and directory names to upper and lower case.
• An option has been added to the mass renaming dialog to evaluate position values from the right. For example, it is now possible to delete the last X characters from a file name.
• The mass renaming dialog now supports regular expressions when deleting specific text from file names.
• The file name preview window in the mass renaming dialog has been extended by several functions that can be used to export the current overview to the clipboard or to a file.

File Search

• The current sort order of a result list is now saved and restored when the application is restarted. Under "View" there are additional options to customize the sorting, including an option to remove the currently set sorting again.
• The selection for usernames in the new "Permissions" filter now includes user groups.
• Refreshing the user interface after deduplication could cause freezing. This problem has been fixed.

01/05/2023

• The options for creating context menu entries are no longer offered to the user in restricted mode. This can be enabled with the /RESTRICTED command line parameter, see the help for more information.
• Numerous other minor fixes and improvements have been made.

11/24/2022

• During the scan, monitors with scaling above 150% could experience regular flickering of the interface during a scan. This error has been fixed.
• The width of the path selection box is now correctly persisted and restored again when the application is restarted.
• The "File extension" column could display incorrect values for folders in an exported file. The column is now exported correctly empty again.

11/07/2022

TreeSize Main Application / General

• The feature to change the file owner, which was already included in the File Search, is now also available in the Details list of the TreeSize main application.
• Portable Installation: If you select a target via "Tools > Create Portable Installation" on which you have already installed TreeSize portable before, the user settings are no longer overwritten there. (Professional edition only)
• In the columns showing permissions, the users and groups are now displayed in alphabetical order.
• The scan overview directly below the ribbon bar is now also hidden in simple mode for a more focused display. This overview bar can still be shown and hidden via on the ribbon bar "View".
• The Details list now indicates possible access errors when displaying folders, instead of simply showing such folders as empty.
• When copying or moving files with the options "Preserve directory structure, starting at level X" and "Apply timestamps for each item" enabled, the timestamps (last modified date) of the source folders are now also applied to newly created folders.
• By pressing Shift during a delete operation, selected objects can be deleted permanently, just like in Windows Explorer.
• An error that occurred when scanning a disk mounted in a folder has been fixed.
• The command line option “/ShowCheckForUpdate False” now hides the update check buttons again as expected.

File Search

• A new filter is now available to search for permissions in file systems. For example, all files or folders to which a user or group has read or write access to, can be listed. Your wish in our feature voting platform!
• Two new search templates have been added to illustrate the new search in permissions feature.
• The performance of deduplication has been significantly improved.
• A new feature has been added to lock specific paths and files. Locked files cannot be marked for a delete operation. This can be used to prevent certain files from being accidentally deleted. Your wish in our feature voting platform!
• Similar to the main application of TreeSize, the File Search now also supports three different program modes: "Expert", "Normal" and "Simple".
• The function for importing file paths has been improved and now works much faster if the checkbox to import only valid paths is checked.
• The progress bar in the lower right corner of the application now shows the progress of the file search, allowing the user to estimate how long a search will take. Statistics from past searches are used for this purpose.
• The component for creating search filters has been extended in the right-click menu by the possibility to invert / negate existing filters. This is a convenient way to change a filter for including certain elements into a filter for excluding them from the result set.
• A new column "Average file size" can now be displayed in the duplicate search. Your wish in our feature voting platform!
• The length of the file name can now be used for a search. It can be selected in the search filter selection under "More search filters". The filter only looks at the name and not the path of a file. Your wish in our feature voting platform!
• When running a scheduled TreeSize task, exports or file operations were not executed in certain situations. This error has been fixed.
• When searching for duplicate files or unique files, an unhandled error could occur under certain circumstances. This problem has been fixed.
• An error that caused filters of the "Name of a parent folder" type not to return all the desired results has now been fixed.

10/25/2022

This update contains 5 Community Features from our Feature Voting Platform: Multi Thread Scans, Mark all except selected, Import and Export of search filters and many more.

New features

• A wizard for new users has been added, which guides you step by step through TreeSize.
• TreeSize now has 3 program modes: "Expert", "Normal" and "Simple". New is especially the “Simple Mode", which aims at casual users with basic knowledge. TreeSize hides functions and settings that are primarily intended for system administrators, in order to provide a cleaner user interface. The "Expert" mode, on the other hand, shows less frequently used settings for power users in the options dialog.
• Copying and pasting folders via the clipboard is now also supported between local scans and remote storage locations such as SharePoint, Amazon S3 or SSH.

File Search

• Using a single search has been made easier. A search can now be started and stopped independently of the rest. When starting a search (for example "Duplicate Search"), the results of the other searches (for example "Simple Search") are no longer discarded, but only those of the started search.
• In the file operations dialogue, the option 'Replace only older existing files' is now also available when moving files to Amazon S3, SharePoint or Linux/Unix servers.
• The search syntax of the 'Simple Search' now offers the 'path:' property, which can be used to restrict the search to specific folder paths. More detailed information and examples can be found in the program help.
• The "Highest search results only" function of the advanced search has been improved. Filtering the results now runs much faster and no longer leads to a short-term blocking of the user interface.
• The function "Select > Duplicates if a copy exists in folder" has been extended so that any folder can now be selected.
• For the duplicate search, a new option "Mark > All except selected" has been added. With this feature, numerous files can be marked for deletion in one step, while the selected file remains.
• Search filters can now be imported or exported from a file using the right-click menu. In addition, a simple list of file names or paths can now be pasted from the clipboard.
• The filter "file extension" has been added to the list of available search filters.
• The search for file content can now also search for terms with special characters in UTF-8 encoded files *without* the so-called "Byte Order Mark".
• When deduplicating, duplicate groups were only included in the operation if all included files were check-marked. This has been fixed so that individual duplicates can now be check-marked for deduplication again.
• The command line option /READONLYMODE "True" is now also correctly evaluated in the file search.
• The duplicate search can now also read and process all files correctly in combination with the option "Search within ZIP files".

Improvements

• The dropdown at the top left of the main window with the last examined paths now enlarges if it contains very long paths, e.g. URLs.
• In the options, up to 64 threads can now be set for a scan in "Expert" mode. Please use this option with care, because many threads working in parallel only make a scan faster if not other factors represent a bottleneck for a scan, otherwise a scan with many threads may become even slower.
• In the dialogue for automated tasks, the value for "Next execution" is now displayed.
• The optional column "Status" now correctly displays the OneDrive file status as text representation. This column can be activated via the "More columns" dialog in the right-click menu of the column header and contains data only for OneDrive folders for which the option "Files on demand" is activated.
• The free space of folders on which Folder Quotas are defined now takes them into account, as it was in V7. In V8, until now, the free space of the entire drive was displayed. You see this value in the status bar, in the optional column "Free space" of the details list, as well as in the tooltip of the directory tree.
• When renaming files, only the file name is now selected by default, but no longer the file extension, similar to Windows Explorer.
• If a non-initialized network drive is scanned (labeled by a red X), TreeSize now tries to initialize it.
• The function to expand to a certain level now folds deeper levels correctly again.
• A problem with the display of size changes for individual files has been fixed.
• An error in the export was fixed: If the option to include files was activated, some files were missing.
• Numerous other minor corrections and improvements have been made.

07/29/2022

• The display of date values in the "Last modified", "Last accessed", "Created on" columns and on the X-axis of the "History" chart was incorrect with certain date settings. This error has been fixed.
• When searching for a user's files from within the user statistics, an incorrect search configuration was generated. This has now been corrected.
• File search: An error when loading certain search filters created with previous TreeSize versions has been fixed.

03/17/2022

This update contains 7 Community Features from our Feature Voting Platform:Allow to pause a scan, numeric file search, find unique files and many more.

File Search

• The duplicate search now also supports a mode to find unique files, i.e. files that have exactly no duplicates. For example, for migrations or backups, you can ensure that two folders are exact copies of each other, even if they are on technically different systems. To do this, simply select "Unique files" as search mode instead of "Duplicate files" or "Duplicate folders".
• The search for duplicate folders has been optimized. Results are now found and displayed even faster.
• Special search filters, such as "Number of pages" for Office files or the width and height of images, can now perform numerical comparisons. Likewise, time intervals can be used to search for date-based filters, such as "Last saved". You can access these by clicking the "More" item at the end of the search criteria drop-down list.
• It is now possible to create new search templates and save them permanently, or to customize existing search templates.
• The language syntax of the "Simple Search" now offers the property "size:", which can be used to restrict the search to certain file sizes. More detailed information and examples can be found in the program help.
• The "accessed:", "created:" and "modified:" properties can now be used in the "Simple Search" to restrict the search to specific time intervals using the language syntax. More detailed information and examples can be found in the program help.
• Result lists can now also be sorted by their checked state, so that all checked files are arranged together at the top of the list.
• When exporting duplicate search result lists to a CSV file, an additional column is now added to make the group membership of the files clear.
• Search filters can now be easily reordered using drag and drop.
• The area for creating and editing search filters can now be expanded and collapsed.

Main module

• The icons in the user interface have been redesigned for a more modern Windows 11 style look.
• The ability to add scan filters in the options has been renewed. The new dialog is more user-friendly and offers additional functions for combining filters. More metadata is now available for filtering.

• Archive files in ZIP, VHD, VHDX or ISO format can now be dragged into the background of the directory tree just like folders in order to analyze them with TreeSize.
• TreeSize is now also available in Norwegian and Polish.
• The "Top 100 Files" have been renamed to "Top Files" and can now be found under the new name in the user interface and help.
• When starting the file search from the main module for a group of scans, all scan targets of the group are now correctly created in the TreeSize file search again.
• The FTP protocol is no longer supported, as already announced in the V8.2 release. Please use the SSH protocol.
• When applying NTFS compression to a folder, not all subfolders and files were compressed. This problem has been fixed.

12/13/2021

This update contains 3 Community Features from our Feature Voting Platform: Search for duplicate directories, search ZIP files and drive image scan.

• File Search: The duplicate search now additionally allows finding duplicate directories. This is a Community Feature - learn more.
• File Search: A new option "Search ZIP files" allows searching for files that are part of a ZIP archive. This is a Community Feature - learn more.
• TreeSize now supports scanning drive images in VHDX, VHD and ISO format. To enter the path, you can use the corresponding image file just like a folder. This is a Community Feature - learn more.
• A new column "Cost" hast been introduced for 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. You can configure the used value and unit to calculate the cost in the TreeSize options.
• Moving or copying files to a ZIP archive is now also supported for remote locations such as SharePoint, Amazon S3 or SSH as destination.
• Intermediate results of subfolders are now immediately included in the displayed results. Previously they were added after the complete subtree has been scanned.
• The Top-100 list now shows intermediate results while the scan is running. The final results are of course available at the end of a scan, when TreeSize has seen all files.
• The scan history is no longer stored in an XML file, but in a SQLite database file. This reduced both the loading time of the history in the user interface and its size on disk.
• The drive overview now optionally displays a column for the occupied disk space. Furthermore, the drive name can optionally be displayed in addition to the drive letter.
• Automated tasks can now also be created with the option "Start with highest privileges" to start them "As administrator".
• When navigating to the parent folder, the previously active folder is now selected in the Details list, as known from the Windows File Explorer.
• Searching for files of a file age has been simplified and can now be started directly from the file age statistics.
• File Search: Result lists sent by email are now sent by default as attachments and not as content of the mail. This means that even large result lists can be sent by email without any problems. This setting can be adjusted in the options dialog.
• File search: The context and ribbon menu for selecting specific files has been revised. The clarity of the menu has been improved and new options provide additional functions for marking specific results in the list.
• File search: The menu bar has been restructured. The clarity of the various functions and options has been significantly improved.
• File search: A new function "Mark duplicates of files in folder" has been added. With this function, it is possible to mark only those duplicates that also exist in a certain directory.
• File search: The user interface for editing search filters has been further improved. When creating and editing search filters, the size of the input fields can now be adjusted with the mouse.
• File search: A new option has been added that allows folding out directories in the search results.
• File search: Performance improvement: Exclusion filters for a specific "Absolute path" now prevent these directories from being searched. Previously, they were still searched and merely excluded from the search results.
• The "Pass items to executable as parameters" function in the file operations dialog no longer passes the items sequentially but in parallel to the executable program to improve the processing speed.
• Destination paths specified in the file operations dialog are now converted to UNC notation if they refer to a mapped network drive. This affects all actions performed using the file operations dialog.
• When copying or moving files with the "Preserve directory structure, starting at level X" and "Apply timestamps for each item" options enabled, the timestamps (last modification date) of the source folders are now also applied to newly created folders.
• When copying or moving files with the options "Preserve directory structure, from level X" and "Apply permissions for each item" enabled, the access permissions of the source folders are now also applied to newly created folders.
• TreeSize now supports paths to SharePoint pages as they can be copied directly from the browser URL.
• For certain files on SharePoint Online, TreeSize previously displayed the date they were saved on the SharePoint. TreeSize now uses the same values here as can be viewed online in the "Modified" column.
• The function "Print right pane" now also includes a visible diagram, if one is enabled. The list alone can still be printed via the context menu of the list.
• For the function to change the owner of multiple files, there is now a button in the ribbon bar in addition to the context menu entry.
• File search: When executing the /DEDUPLICATE command line parameter, the full list of duplicates is now deduplicated again as expected.
• SSH scans now support the EdDSA host key algorithm Ed25519.
• Bugfix: A bug with calculating MD5 and SHA256 values via SSH was fixed.
• Bugfix: A problem with displaying Chinese characters in exported PDF files was fixed.
• Bugfix: When copying or moving multiple files within an SSH (Linux/Unix) scan, not all files could be copied/moved under certain circumstances. This problem has been fixed.

Changed compatibilities

• TreeSize now requires .NET Framework 4.8, which should already be installed on most systems via Windows Update.

Main module:

• It is now possible to scan your Amazon S3 Storage using TreeSize.
• It is now possible to scan Linux/Unix-servers via SSH-protocol using TreeSize.
• It is now possible to add single file types or users as columns to the “Details” view using their context menu. That way they can be easily monitored across the entire folder hierarchy and can also be included in the reports.
• Intervals of the Age of Files statistics can now be added as columns to the “Details” view using their context menu.
• The number of files in the Top 100 list can now be configured in the Options dialog. Additionally you can choose here whether they will be chosen based on their plain file size or the space they actually occupy on the disk.
• A new checkbox on the ribbon bar “View” allows to hide empty folders. This is particularly useful if there a lot of such folders because a filter has been applied.
• Beneath the user and the file extension statistics we show a treemap chart now, because it is able to transport more information on the same area as the old bar chart.
• We added two additional formats for displaying usernames: Full Name, and Username (Full Name)
• A new tooltip option allows you to peek into a folder without actually expanding the folder in the directory tree.
• TreeSize may now optionally show a message in the Windows system tray, once a longer running scan or file search is finished.
• The treemap chart has been extended with many new display options:
  • Single files can be displayed now.
  • Besides the file types now the file type groups like „Office files“ or “Video files” can be optionally shown as intermediate level. If shown, they will be colored by type, not by their level like the folders.
  • The free space can optionally be shown as separate tile.
  • Optionally the labels can be hidden so that no space needs to be reserved for them.
• At „Options > Scan > Filter“ you can now choose entire file type groups like „Office files“ or „Video files“ as filter, just like this is now possible in the Custom Search (see below).
• When scheduling a scan you may now choose a monthly interval. (Professional edition only)
• The user interface is no longer blocked when loading or comparing with a formerly saved XML file.
• The column width of PDF exports can now be configured in the Options dialog.
• The feature “Hide folders smaller than…” can now be configured using KB, GB and Bytes besides MB.
• Numerous minor improvements and fixes have been included.

File Search:

• Like in the main module Amazon S3 Storages and Linux/Unix-Server via SSH can now be used as search target.
• In the Custom Search you can now use the existing file type groups like “Video files” as search criteria. These groups can also be edited now in the Options dialog of the TreeSize File Search.
• All columns the Windows Explorer supports can now be displayed and exported, among them the width and height of pictures, the number of pages of MS Word documents, or keywords of JPG and Office files.
• Multiple custom searches can now be defined and used concurrently.
• The minimal and maximal directory depth can now be used as search criteria in the custom search.
• The predefined searches like “Biggest Files” now have their own ribbon bar, in which the configuration for this search is done now.
• It is now more comfortable to choose date values in the Custom Search.
• The feature “Checkmark if…” now offers more possibilities and regular expressions.
• The TreeSize File Search now supports PDF export too.
• The number of errors (like “Access denied”), which occurred during the search, is now displayed in the status bar. Clicking it brings up a dialog with further details.
• Duplicate Search: The duplicates can be exported optionally with groups now. Such a text file can now be properly imported to the duplicate search.
• Duplicate Search: In the dropdown menu of the button “Check all but newest” we now offer more functions to modify the check-state of the results. Here, an option can be activated that ensures that at least one duplicate remains after deleting duplicates.
• The export of the Duplicate Search has been accelerated by factor 10.
• A new option for scheduled searches will send an email only if results have actually been found for this search. (Professional edition only)
• The command line option /SORTBY has been introduced, which is now also supported in the TreeSize File Search. (Professional edition only)
• The new command line option /COPYTO has been added, it works like the existing /MOVETO function but copies the search results. (Professional edition only)

Compatibility changes:

• Windows XP and Windows Server 2003 are no longer supported.
• On Windows Core Server only the command line interface is supported, a user interface is no longer available. In case this is still needed, V6.3.7 can be used. V7.0 prints the results as text on the console for a given path. This also applies to the File Search, which can be started using the /SEARCH parameter, additionally a search pattern can be supplied using /FILTER, or previously saved search options can be supplied as XML file. (Professional edition only)
