9 February 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.

7 November 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.

25 October 2022

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.

10 August 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.

17 March 2022

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

• Windows 7 and Windows Server 2008R2 are no longer supported, so at least Windows 8.1 or Windows Server 2012 is now required. Older versions of TreeSize that support older operating systems can be downloaded from our customer area.
• We plan to end support for the FTP protocol with V8.3, because we believe that wherever FTP is possible, the more modern and secure SSH protocol is also usable. If we are wrong with this assumption, we would be happy to hear from you. On our feature voting platform there is also an entry for the support of the modern SFTP / SCP protocol.

This fixes issues that some customers have experienced with the Windows Address Space Layout Randomization (ASLR) security option, Carbon Black security software, and Lumension Endpoint Protection. Therefore, all customers need new installation keys for V8, which are available through our customer area.
• A new dialog for selecting a scan targets has been added. Even complex paths and URLs can now be compiled with a few clicks.
• A search box at the top of the main window (available in Windows 10), as well as in the Options dialog, now allows searching for actions or settings quickly and conveniently.
• Scans of network drives are now up to ten times faster.
• Explicitly added network drives and UNC paths are now displayed in the drive overview even if they are currently not accessible.
• The function for restricting the view to one file extension has been improved and allows a restriction to a complete file group.
• The "Name" column is no longer scrolled out of the visible area in all lists. This makes it easier to view tables with many activated columns.
• Screen scaling for multiple monitors with different resolutions has been improved.
• If a drive locked with BitLocker is scanned, the dialog for entering the password now appears automatically if the drive has not been unlocked yet.
• Bugfix: The progress bar when comparing a scan with another path now starts at 0 instead of the number of files in the original scan.

Directory Tree

• The small progress bar in the directory tree has been visually modernized. It now scales correctly on high-resolution monitors for which Windows screen scaling is enabled.
• A file selected in the directory tree is now opened or executed by pressing Enter.

Details list

• In the Details list, checkboxes can now be displayed for the individual elements to simplify complex selections. File operations such as copy, move, rename or delete can then be applied to the selection.
• The background context menu of the Details list has been extended and now allows further actions, such as creating a new folder.
• The preview pane on the right of the Details list and the File Search results now shows more metadata, like: File version, keywords, "Last Saved By" for office files, etc.
• For EML, EXE and DLL files, the "Author" column now shows available values of the file.

Charts

• All charts that show a part of the directory hierarchy now have a button to navigate up one level in the hierarchy. As before, you can navigate downwards in the hierarchy by double-clicking an element.
• The history now offers the option to display sizes of older scans for which different filters were used in the scan options, which may limit the comparability of results. The new option "Ignore Scan Filters" can be found in the ribbon bar "History" under "Show".
• An error was fixed in the file age statistics for the number of files displayed.
• The pie, bar, and tree map charts now also take a restriction to a file extension or a user into account and thus show the same values as in the directory tree and the Details list.

SharePoint

• TreeSize now also supports multi-factor authentication when accessing SharePoint Online.
• The number of versions of files on a SharePoint are now correctly displayed in the corresponding column of the details list.
• When examining SharePoint servers, the file attributes are now determined correctly.
• For files and folders on SharePoint servers, available values are now displayed in the "Description" column.
• TreeSize now also supports the display of free and total available disk space on SharePoint pages.

Amazon S3

• The syntax to scan all available Amazon S3 buckets has changed from s3:// to s3://* to be more consistent with similar cases. If you supply credentials within the URL please use: s3://Key:Hiddenkey@*
• You can now also delete folders from Amazon S3 Storage that contain non-empty subfolders.

SSH / Linux Scans

• The available file operations for SSH scans have been extended. For example, it is now possible to create new folders in scanned SSH structures.
• SSH scans now support the ECDSA host key algorithm.
• The "Permissions" column now also shows the file permissions for SSH scans using the common Linux/Unix format. This applies to all lists in which the "Permissions" column is available ("Details", "Top 100 Files", file search result lists).

Export

• Column headers are no longer truncated when exporting to text format and plaintext emails. Instead, they are wrapped to multiple lines if necessary.
• The file export in HTML format now includes all graphics in the HTML file. Previously, graphics were stored as individual files next to the .html file. As of now they are embedded. This change makes it more convenient to move or forward HTML exports. For technical reasons, this increases the runtime for HTML exports and the size of the resulting HTML file.
• When selecting the export options, you can now choose whether an additional "[Files]" element should be exported for each directory.
• The font used for PDF exports is now based on the system settings and the current application language. This means that Asian fonts can now be correctly exported to PDF.

Command line (Professional Edition only)

• Using the parameters /EXCEL /APPENDTOFILES False, existing Excel files can now be completely overwritten during export.
• The new parameter /EXPORTTITLE allows to configure the title line in exports. The /TITLE parameter can still be used to replace the path with your own text for a single scan, or to change the name of a custom file search.
• When exporting to an Excel file via /EXCEL, the /APPENDTOFILES parameter can now be used together with /SHEETNAME to append the data to the specified sheet.
• The new parameter /IMPORTPATTERNS can be used to load filters from a file.
• For XML exports, the /DATE parameter now adds the date before the .XML.ZIP file extension, instead of between .XML and .ZIP as before.
• PDF files are now correctly attached to email exports with multiple scans (when exporting from the command line).

File operations

• The File Operations dialog now provides separate radio buttons for selecting the move and copy operations.
• The “Move Elements to Recycle Bin” and “Delete Elements from Hard Disk” options have been merged to “Delete Elements” item. Using the new “Move to Recycle Bin” checkbox, elements can still be moved to the recycle bin (if supported for the drive).
• When selecting “Zip Items”, there is now an additional option “Keep original items after zipping” which prevents the zipped files from being deleted from their original location.
• The File Operations dialog now also allows to move or copy files to Amazon S3 Storages, SharePoint or Linux/Unix servers.
• The usability of the dialog for renaming multiple files at once has been improved

File search

• 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)

  • 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).

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.

Comparing / Trend Analysis

• Compare using historic snapshots: TreeSize now facilitates comparing the current state of your local disk space with previous points in time using snapshots. No files need to be exported, even pre-existing snapshots that have been created by the system before TreeSize was installed can be used for comparison. Additionally, TreeSize offers an option to create a snapshot ("Tools > Create Snapshot").
• Toggle between size growth and current size: After performing a compare using an exported XML file or a snapshot you can now toggle between a comparison mode showing the size changes in all controls, and the mode showing the current values. In addition you can enable new columns ("Growth" and "% Growth") presenting the size increases and decreases in any of these modes on the "Details" tab. Those columns are not activated by default, but can be enabled using the context menu of the "Details" list header.

User Interface

• On Windows Vista / Server 2008 and higher, a ribbon-style user interface is now used. We decided to use the Windows Ribbon Framework to create the new user interface for TreeSize. The Windows Ribbon Framework is part of the operating system in Windows Vista and later and so ensures optimal support and integration also in future Windows versions. It is also used by MS Paint, MS WordPad, MS Movie Maker and the Windows 8 Explorer. On Windows XP/2003 you will still see the classic user interface with a main menu bar.
• The "Options" dialog has been redesigned. Several new options especially for exporting have been added (see next section). A new checkbox "Expert mode" allows activating a mode that shows additional options that can be useful for experienced users.

• Duplicate Files: You can now define filters for the duplicate file search to include/exclude files whose file name, path or owner match certain patterns ("File Search > Duplicate Files > Filters"). Please note: Using a highly selective filter for the duplicate search will remarkably increase the performance of the search, since fewer files have to be compared.
• Temporary Files: If all files contained in a directory are matching the temporary file search criteria, the result list will show only this directory on the first level. The directories identified as temporary can be expanded to show subfolders and files.
• Move Checked Files: Added new option to create an undo-script for move and copy operations (section "Logging").
• Move Checked Files: There is now an option to replace existing files instead of resolving the name conflict using an automatic renaming.
• Move Checked Files: For move and copy operations you can now define the directory level that should be preserved from the source directory structure.
• With the new function "Change File Owner" included in the right click menu of the search result list you can now easily set a new file owner for all selected files. This is very useful e.g. if you found a group of files with an invalid file owner.
• You can now use wildcards when scanning servers using server names (e.g. \\serverA*\) or for scanning IPv4 class C nets (e.g. \\192.168.123.*).
• The new columns "Allocated Space" and "Dir level" have been added to all search result lists. The new columns are deactivated by default but can be activated via the context menu of the result list header or through "View > Visible columns".
• A new "master" checkbox for (un-)checking all objects in a result list has been added to the top left of the header line.
• Internet Files: Added support for Google Chrome and enhanced support for latest versions of other browsers (IE, Firefox and Opera).

Drive List

• The Drive List now shows the S.M.A.R.T. status of the listed drives (if accessible). Drives at risk can be identified quickly this way.
• The Drive List can now also be exported to an Excel file, either using the right click menu or the command line option /EXPORTDRIVELIST.
• The Drive List now has its own menu bar which contains commonly used actions such as mapping a network drive. The menu is shown as a Ribbon context tab, as soon as the Drive List has been clicked. (Windows Vista and higher only)
• The Drive List now supports importing a list of paths from the clipboard using the right click menu. The menu item will only be shown if the clipboard contains a valid path.

Scheduled scans / Command Line Options (Professional Edition only)

• The dialog to create and edit scheduled TreeSize tasks has been revised and new options have been added. For example, scans can now be scheduled not only daily and weekly but also monthly and you can force not to show the user interface. In addition you can now choose if exports should be appended to existing files, choose a column by which the exports should be sorted, and supply an XML file including the configuration for the scan. Find a detailed description of the new "Schedule Tasks" dialog, including all options here.
• The new command line option /USERFILTER has been added: It allows predefining the user by which the directory tree is filtered.
• The command line parameter /NOUNITS now also prevents thousands separators in exported values.
• With the new command line switch /AGEOFFILES you can export a textual representation of the "Age of Files" statistics.
• Added command line parameters /SHORTDATEFORMAT, /HIDESMALLFOLDERS and /SORTTYPE. See Command Line Options for details.

• The information on the history tab can now be exported or imported.
• The new column "Link Target" has been added to the "Details" tab and all export options. Columns "User Comment" and "Title of Scan" have been removed. New columns are not activated by default, but can be enabled using the context menu of the list header or at "Tools > Options > Export".
• The column "Permissions" now shows "full" instead of "+w+r+x" if a use has full access rights on a file or folder. This allows distinguishing if a user has just read/write privileges or full access to a folder (which includes changing security attributes and taking ownership).
• After copying a file system object to the clipboard in the Windows Explorer using Ctrl+C, its full path will be pasted to the Folder dropdown box of TreeSize when pressing Ctrl+V.
• When scanning an entire server using \\ServerName you no longer need to enable the virtual root folder to group the shares under a common folder.
