Bugfix: An unhandled error that could occur when sorting by the column "Growth %" on the tab "Details" has been fixed

The Amazon S3 regions eu-west-2 (London) and eu-west-3 (Paris) are now supported.

Bugfix: When saving a scan to an XML file ("File > Save Scan to XML File") an error occurred if at least one file type, file type group, user or file age was previously added as a column to the Details list and this was also activated in the XML export options ("Tools > Options > Export > XML > Exported Columns"). This error has been fixed.

The error handling of the TreeSize dialog for scheduled scans has been further improved. (Professional Edition only)

Bugfix: When moving files using the "Move Elements" dialog with preservation of the permissions / access control lists (ACLs), for newly created folder the inheritance of the ACLs is now also copied correctly.

Amazon S3: In a folder with many subfolders, potentially not all subfolders were found. This problem has been fixed.

File search: When using the command line parameter /OPTIONS, TreeSize now checks if the option file exists and aborts processing in case of an error. (Professional Edition only)

Exports of the directory tree, for which the columns of the Details list are configured to be used, now consider all columns displayed in the Details list.

In the directory tree, TreeSize now shows again, as TreeSize V6 did, the name of the drive behind the drive letter, if a name was assigned.

Some other minor fixes and improvements have been incorporated.

Changes in V7.0.2 (28 Jun 2018)

Depending on the current user settings, updating from a previous to the latest version of TreeSize could cause some issues. This could occur more likely, when updating from very old versions of TreeSize. These issues are now resolved.

Fixed a possible crash that could occur if two usernames differ in case only.

OneDrive folders are now followed correctly again. An issue with the latest OneDrive client has been resolved.

Comparing a scan with a previously exported scan from an XML file that contained multiple drives, could fail under certain circumstances. This issue has been fixed.

File Search: When sorting by the column “Allocated” an error message will no longer occur.

A few minor fixes and improvements have been incorporated.

Changes in V7.0 (01 Jun 2018)

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:

oSingle files can be displayed now.

oBesides 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.

oThe free space can optionally be shown as separate tile.

oOptionally 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)


Changes in V6.3.7 (12 Apr 2017)

A few minor fixes and improvements have been incorporated.

Changes in V6.3.6 (19 Jan 2017)

Bugfix: The column "File version" now displays the file version from EXE and DLL files, and no longer the product version. The advantage of the file version is that it typically has more digits and a fixed format, while the product version can be any text.

Bugfix: "File Open" and "File Save" dialogs work as expected again on Windows Core Server.

Bugfix: An error that occurred when trying to scan folders on a mobile device on Windows Insider build 14986 has been fixed.

A few minor fixes and improvements have been incorporated.

Changes in V6.3.2 (06 Jul 2016)

Our MSI-installer now requires an installation key. Unattended installation using the MSI-installer is still supported. Please refer to the chapter "Installation" in our help to learn how to pass the installation key as a command line parameter.

TreeSize now takes the new NTFS compression features of Windows 10 into account as long as the option "Tools > Options > Scan > Track NTFS-specific features" is switched on. Please note: Files that are compressed using these new algorithms are not flagged as compressed by Windows in the file attributes.

A new option to deactivate the drag and drop features of TreeSize has been added to "Tools > Options > View > General" (requires activating the "expert mode" checkbox). Turning off drag and drop should prevent unwanted changes on critical systems.

Bugfix: The use of the command line option /EXTENSIONSLIST in combination with /NOGUI no longer exports incomplete files.

Bugfix: When calculating the allocated space, the correct cluster size is now used on drives with the ReFS file system.

Bugfix: The XML export now correctly respects the setting "Options > XML > Export expanded elements only".

Bugfix: The command line option /EXPAND 1 now also works  if files shall be exported along with the folders and the root folder contains no subfolders.

Bugfix: For other domains than the current domain, SIDs are now resolved again correctly to usernames in the "Owner" and "Permissions" columns.

Bugfix: The feature "Expand > Set Size" now works for values greater than 2,048 MB.

Bugfix: The chart on the "History" tab was empty if an exclude filter was defined in the "Options" which effectively excluded files.

Bugfix: The date columns did not contain any values in exported Excel files under certain regional settings (e.g. Czech on Windows 8). This is no longer the case.

Bugfix: The "Find" dialog of the Directory Tree (Ctrl+Shift+F) could raise an error after continuing the search from the beginning. This problem has been fixed.

Bugfix: After changing the view type (e.g. from "Size" to "Allocated Space") the charts on the "Age of Files" and "History" now update instantly.

Bugfix - File Search: When moving files for which you do not have sufficient access rights for deleting them to a ZIP-file, the move operation is no longer interrupted with an error dialog.

Bugfix - File Search: If both a filter for a file name/path and for the owner or file content is applied, this set of filters now only matches in case all filters match. This reestablishes again the behavior of TreeSize V5.5 in cases when both a filter for the file path and file owner were defined in the Custom Search.

Bugfix - Duplicate File Search: For files that have been deduplicated using hardlinks, the remaining physical file now receives the correct union set of permissions.

Several minor fixes and improvements have been incorporated.

Changes in V6.0.2 (10 Dec 2013)

Bugfix: Under certain conditions a certificate error occurred during application startup which prevented TreeSize from further execution (Certificate Error: -2146762487). This is no longer the case.

Bugfix: The Personal edition can once again scan network shares of computers that aren't part of a domain.

Bugfix: In the "Own Permissions" column, the permissions of the parent folder were shown for certain files. This error has been fixed.

Bugfix: When deleting multiple files in the "Details" view, some elements were not removed under certain conditions. This error has been solved.

File Search: Support for sending email via command line and attachment of files has been improved. It now matches the function of the main module.

The "Find in Directory Tree" feature (Scan > Directory Tree > Find) now supports full paths.

A few minor fixes and improvements have been incorporated.

Changes in V6.0.1 (11 Nov 2013)

The dialog that allows selecting a snapshot for comparison now shows not only the date but also the time of the snapshot.

File Search: When importing previously saved search options users can now decide using a checkbox whether the view options (like the used unit or the number of decimals) should be loaded from the file as well.

Deleting entire folder branches in the Directory Tree using the keyboard shortcut "Shift + Del" is faster now and no longer complains about non-empty directories in rare cases.

Bugfix: In some cases the reading of the Master File Table (MFT) was very slow. This problem occurred only if local drives were scanned with administrative privileges and a certain structure was present in the MFT. This problem has now been fixed.

Bugfix: On Windows 2008 systems which did not have the VeriSign 2010 root certificate installed and did not have the automatic root certificate update of Windows turned on, TreeSize was closed without an error message a few seconds after the start of a scan due to a failed certificate check.

Bugfix: Deleting items from the Details list using the keyboard shortcut "Shift + Del" now deletes all selected files.

Bugfix: The selected sort order (by name or by size) is now used also for all exported files.

Bugfix: When TreeSize is using more than 4GB of RAM error messages no longer appear on the "Chart" tab.

Bugfix: Loading a previously saved XML file for a drive which is not present on the current system no longer leads to an error message on the Top 100 page.

Bugfix: Excel export is now also possible in the Personal Edition as announced for V6.0.0.

Bugfix: If the feature "Generate expandable/collapsible Excel export" is selected in an exported Excel file, single files are now shown in the correct group.

Bugfix: In the Duplicate File Search the ribbon button "Check all but newest" is now enabled.

Bugfix: The feature "Expand > Hide small folders" is now working correctly, even if the number of files are shown in the Directory Tree.

Bugfix: Exported HTML files were missing single files if the option "Include single files in export" was activated, but single files were not shows in the Directory Tree. This is no longer the case.

Bugfix: In rare cases, the column "Inherited Permissions" contained wrong values.

Bugfix: Support for Unicode characters in emails has been improved.

Bugfix: The full version is no longer creating a folder "DbgLogs" in the user's documents folder.

Bugfix: The combination /NOGUI /GROUPSCANS /TREEMAP of command line parameters is no longer producing an empty treemap chart in the exported file.

A few minor fixes and improvements have been incorporated.

Changes in V6.0 (24 Sep 2013)

Faster scans: The well-proven and extremely fast search technology of UltraSearch working directly on the NTFS file system structures has been incorporated to increase the performance of TreeSize scans and searches on local drives.

64 Bit: TreeSize is now available as native 64 bit application (Professional Edition only). When scanning very large file servers memory will no longer pose a restriction.

A new option allows making folders and [Files] items expandable and show single files in the directory tree.

New license keys will be issued for V6. Please note: The old license keys for V5 provided on the license documents will not be valid for V6. The new license keys can be obtained in our customer area.

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.

The include/exclude filter in the "Options" dialog has been revised. It offers matching by regular expression, exact match, filtering by owner and offers a preview of the impact of a filter in an Explorer-like view.

Support for Windows Vista/7 style drag icons and drag hints has been added.

You can now search the directory tree for a specific file or folder ("Scan > Directory Tree > Find" / Shift+Ctrl+F).

The number of errors that occurred during a scan (e.g. access denied errors) is now shown in the status bar. Clicking it opens a dialog with detailed information regarding the errors.

Export Features

The HTML export has been revised: When JavaScript is enabled, you will now see 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.

Email: Besides sending emails using your MAPI client it is now possible to send them through SMTP as well. This is useful when sending emails from within scheduled tasks. The SMTP setting can be configured at: "Tools > Options > Export > Email > Transport"

You can now choose whether file information for single files should be included in Excel, HTML, Text and Printed export ("Tools > Options > Export > Exported elements").

You can now choose whether an Excel export of the directory tree should support expandable / collapsible levels ("Tools > Options > Export > Excel > Expert Mode > Formatting").

The type of information exported to an XML file can now be configured.

The Personal Edition now supports the same export features (Excel, HTML, and Text files) as the Professional Edition.

File Search

Custom Search: The pattern editor of the custom file search has been revised. It now supports regular expressions and also allows users to search in the file content.

Custom Search: You can now search for both files and folders at the same time (tab "Size / Attributes").

Custom Search: You can now decide whether your search filters shall filter by the number of NTFS hardlinks of a file. The new options "Ignore NTFS Hardlinks" and "Minimum Number of Hardlinks" are located on the "Other filters" tab.

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.

Minor changes and improvements

The path in which the history information is stored can now be adjusted. This allows sharing this file among several users / administrators.

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.

Numerous further improvements have been incorporated.

Bug fixes

Bug fix: "File > Export > Send by Email" now works under Windows Vista/7 even if TreeSize was started as administrator and MS Outlook is the default email client.

Bug fix: On some Windows Vista based systems TreeSize got into a not responding state when getting back from screensaver.

Bug fix: An occasional problem with corrupt Excel exports in XLSX-format has been solved.

Several minor bug fixes have been incorporated.


Changes in V5.5.5 (30 Mar 2012)

Custom File Search: The values for min and max size now also work for directories. This allows you  e.g. to easily find folders that do not contain any files by setting the max size to 0 and checking only "Directory" in the Attributes list.

Bug fix - File Search: Some MD5 checksums could be missing in exported files.

Bug fix: Editing the execution time of an existing scheduled TreeSize task did not work.

A few minor fixes have been incorporated.

Bug fix: When selecting "Remove from TreeSize temporarily" in the right click menu of the "Details" list sometimes too many items disappeared from the list.

Bug fix: Pressing the "Del" key in the "Details" list deleted only the selected files if both files and folders were selected.

Bug fix: TreeSize Professional now follows Windows DFS shares correctly again and shows their target path in the tooltip window.

Bug fix: The command line option /FILEAGESCHART no longer produces empty charts.

Bug fix - File Search: Using a wildcard pattern like "C:\Temp\*.txt" in the Custom File Search now produces the expected result and lists all text files in the directory branch "C:\Temp".

A few minor fixes have been incorporated.

Changes in V5.5.3 (24 Oct 2011)

Bug fix: An occasional repaint problem of the folder dropdown box on the top left of the main application has been fixed.

Bug fix - File Search: "Edit > Check all matching a pattern" now also works correctly for the duplicate search and now considers not only the full path but also the file name. This allows using more simple patterns like "New*.txt".

Bug fix - File Search: The behavior of the command line option /MOVETO has been improved.

A few minor fixes have been incorporated.

Changes in V5.5.2 (10 Aug 2011)

Bug fix: Saving an XML report for a virtual root folder caused an error, this also applied to the command line options /GROUPSCANS /XML.

Bug fix - File Search: An error was fixed that occurred when merging the permissions for deduplicated files.

Bug fix: Entering paths like \\Server\A* in the edit field on the top left of the TreeSize window is now working again.

File Search: The custom file search now allows again a minimum value of "0" for the date fields "Since XX days". This allows to search for files that have been created, changed or accessed today.

Personal Edition: The menu item for comparing XML reports is now available again.

Changes in V5.5 (18 Jul 2011)

The new columns "Inherited Permissions" and "Own Permissions" have been added to the "Details" tab and all export options. The column "Own permissions" simplifies finding folders that do not inherit all their permissions from their parent folder. Both columns are not activated by default, but can be enabled using the context menu of the list header or at "Tools > Options > Columns/Export".

The new column "Alternate Data Streams" in the Details list shows the size of NTFS alternate data streams in a file.

The columns "Quota Limit" and "Quota Usage" have been added to the "Users" list. This allows a quick overview about the usage and limit of the Windows built-in quota features from within TreeSize.

The "File" menu now includes a list of recently scanned paths and recently saved XML reports.

You can now scan paths like "S:\Users\R*" or "R:\*\MyVideos". Only one root folder will be created in this case.

File Search - Move Checked Files: It is now possible to burn the checked files to an optical media.

File Search - Move Checked Files: Because of many customer requests, it is now also possible to copy all checked files to a different location instead of moving them.

File Search: It is now possible to check or uncheck all search results which are matching a certain pattern using the "Edit" menu.

File Search - Duplicates Files: It is now also possible to search duplicates solely by their file name.

File Search - Duplicates Files: The deduplication feature 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.

File Search - Duplicates Files: When deduplicating files using hardlinks now a union set of the original access privileges is applied to the remaining file, so that all users can still access the resulting file.

File Search - Oldest Search: You may now alternatively specify the minimum age of a file in number of days instead of a certain date.

The saved XML reports now include the owner of each folder in case the file owner statistics was turned on in the Options of TreeSize.

TreeSize is no longer shown in the context menu of virtual folders like the recycle bin. It is now also available in the background context menu of folders.

Bug fix: The command line option /SCAN did not work in combination with /EXCEL and /TEXT.

Bug fix: The command line option /TREEMAP did not work in combination with /NOGUI.

Bug fix: Right clicking on a very large file could cause the application to freeze for several seconds as this triggered calculation of checksums shown in the "TreeSize" submenu of the right click menu.

Numerous further improvements and a few minor bug fixes have been incorporated.

Changes in V5.4.4 (13 Dec 2010)

Now the language which is chosen in the first step of the installer decides about the language of the user interface, the regional settings of the system are no longer taken into account.

Bugfix: If the TreeSize File Search is added to the Explorer context menu using the option at "Tools > Options > Miscellaneous", the correct caption for this menu item is used now.

Bugfix - File Search: The results of the search type "Internet Files" were possibly incomplete.

A few minor fixes and improvements have been incorporated.

Changes in V5.4.2 (22 Oct 2010)

Bugfix: An error when exporting the settings at "Tools > Options > Miscellaneous" has been fixed.

Bugfix - File Search: When moving files, the "Yes to All" button is confirms all further confirmation dialogs of the same type.

A few minor fixes and improvements have been incorporated.

Changes in V5.4.1 (06 Oct 2010)

The default sort order of the "Top 100 Files" list is now again descending by size.

Improved saving and restoring of the toolbar positions

File Search: Scrolling in the duplicate list could be slower than in V5.3 if the columns "Creation Date" or "Last Access" were visible.

Bugfix: On a few systems with Outlook 2003 an error in MSMAPI32.DLL occurred on startup of TreeSize.

Bugfix: The toolbar button for copying the history chart to the clipboard was always disabled.

A few minor fixes and improvements have been incorporated.

Changes in V5.4: (21 Sep 2010)

Paths that are exported to Excel files are now exported as clickable hyperlinks. This allows you to quickly jump to the appropriate path in Windows Explorer.

The automatic mode for size units ("View" > "Automatic Units") is now also supported for the export to Excel files. Please note that it will be difficult to do calculations based on these values.

Personal Edition: TreeSize Personal now scans network drives if the computer running TreeSize Personal is not part of a Windows domain and the remote system is not a Windows server. This enables customers of the Personal Edition to scan network drives in their home network, including NAS systems based on Linux and Samba 3.

All lists, including the results lists of the file search, can now be saved in HTML and RTF format by choosing the appropriate format in the "Save" dialog.

All printed lists now include the icons, text formatting and indents.

Printed reports now show compared scans in red and green, just like on the directory tree, if the option "Use bold Text and Colors for Printed Reports too" is activated in the Options dialog.

The tree map on the "Charts" tab now not only supports drag operations but also drop operations. Additionally, drag operations with the right mouse button are possible as well. The right click menu of the tree map now offers the possibility for elements like *.doc to list all files that belong to this element.

The progress of the currently selected scan is now indicated in the Windows 7 task bar.

The indicated progress of a scan is now calculated more exactly by using the results of previous scans (if available).

Options: On the new tab "File Groups" the file groups shown on the "Extensions" tab can now be customized.

The incremental search, which is started when you type characters in the directory tree on the left, now searches all sub folders, even the ones that are not visible or expanded. This allows you to quickly locate folders by starting to type their first characters.

A new option (Tools > Options > View) allows you to display folders containing long paths (> 255 characters) in red.

Drives are now displayed in the directory tree including the volume name, e.g.: C:\ (System)

The new command line option /SHEETNAME allows you to specify the name of the Excel sheet that will be added when using the /EXCEL command line option. See help for details.

History: The new option "Purge Old History Values" in the context menu of the "History" tab can be used to permanently remove older values from the chart.

The small chart on the bottom of the "Extensions" and "Users" tab can now be exported in scheduled tasks as well.

The Windows defragmenter can now be started from the TreeSize "Tools" menu.

A new option (Tools > Options > Startup) allows you to always start TreeSize as administrator for Windows 7 and Vista, not just if the appropriate entry from the Windows Start menu has been used.

If TreeSize is started non-elevated and it encounters a folder which it does not have access to, it now asks the user if TreeSize should be started again with administrative privileges.

The Include Filter at "Tools > Options > Include/Exclude > Include" now supports paths and path fragments, too, not only file extensions. A dialog for editing the pattern more comfortably can be opened using the button on the right.

The shortcut for copying the selected entries of the Details list to the clipboard as text 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.

The shortcuts Alt+Left, Alt+Right and Alt+Up now behave like in Windows 7 Explorer.

In the Restricted mode, which can be started using the command line switch /RESTRICTED, the Explorer context menu is now available in the directory tree, the Details list and the Top 100 list.

A new option under "Tools" > "Options" > "Miscellaneous" allows you to add the TreeSize File Search to the Explorer context menu of folders and drives.

File Search: The Duplicate file search now supports SHA256 check sums. While it is very unlikely that the MD5 hash algorithm produces the same hash value for different files, the SHA256 algorithm further reduces the statistical risk of such hash collisions.

File Search - Custom File search: The tabs of the custom file search that have filters set (= have actual influence on the search result) are now marked by a bold text in their tab.

File Search: The File Search now decides, in a more intelligent way, if it should match a given pattern against the full path or just against the file name. In previous versions it was difficult to keep certain substring matches out of the search results. Additionally, you can now use quotes around your search pattern and so force a strict matching.

File Search: It is now possible to search for files that do not have a certain attribute set.

File Search: The export format of the Duplicate files list has been improved: The groups are easier to identify because files are indented now.

File Search: A new option "Show Time with Date Values" was added to the "View" menu. It allows you to turn on or off the displaying of the time values next to the date values.

File Search: The right click menu of the drive list on the "Search Options" tab now has a feature to import and add paths from a text file.

Bugfix - File Search: If the "Move Checked files" function needed to create a new directory in the root of a drive, it sometimes had the hidden and system attribute set.

The support for Windows 2000 has been dropped because Microsoft dropped it in July 2010. TreeSize V5.3.4, which is compatible with Windows 2000, remains available in our customers area for registered customers with valid maintenance.

Several minor improvements have been incorporated.

Changes in V5.3.4: (21 Jan 2010)

If single files are deleted from the "Details" list, the size in the directory tree will now be updated even if "Automatic Updates" are turned off.

Bugfix: On systems that are not part of a Windows domain, delays could occur when expanding items in the directory tree or when the information for the long hint text was compiled.

Bugfix: In the column "Permissions" sometimes usernames were not displayed correctly, instead "S-1-0" was displayed.

A few minor improvements have been incorporated.

Changes in V5.3.3: (11 Dec 2009)

Bugfix - File Search: A long list of duplicate files could contain invalid items in some cases. This caused an error if the list was scrolled to the bottom or if it was exported to a file.

Bugfix: "Show Files" in the right click menu of the "Age of Files" chart as well as a double click on one of the bars produced empty result lists on some systems.

Bugfix - File Search: When loading search options from an XML file, the date values were not restored correctly on some systems.

Changes in V5.3.2: (24 Nov 2009)

Environment variables can now be used in paths to be scanned, e.g. if they are entered in the directory dropdown box in the top left of TreeSize or passed via command line.

The function to list files of a user / extension / file age interval now takes the currently set exclude filters into account.

File Search: The search progress is now visualized in the Windows 7 task bar icon.

File Search: The Explorer context menu is now also displayed if more than one file is selected, as long as the selected files are on the same drive or share.

Bugfix: Tools > Options > Include/Exclude > File Types: Multiple patterns separated by blanks were no longer working correctly.

Bugfix: The exclude filter did not work for patterns with an absolute path. As a consequence, the feature "Remove from TreeSize (permanently)" in the right click menu of the directory tree did not work too.

Bugfix: The shortcut "Ctrl" + "-" for the feature "Remove from TreeSize (permanently)" did not work.

Bugfix - File Search: It was no longer possible to enter a server name as origin for the search (e.g. \\Server1).

A few minor bug fixes and improvements have been incorporated.

Changes in V5.3.1: (15 Oct 2009)

Bugfix: The regular check for update could crash TreeSize on application start.

Bugfix: After using "File > Compare With XML Report", folders could appear multiple times in the directory tree.

Changes in V5.3  (12 Oct 2009)

TreeSize has passed the "Compatible with Windows 7" logo test.

Introduced new toolbar buttons "Back" and "Forward". You can use these buttons to navigate like in the Windows Explorer.

In the directory edit field in the upper left corner of TreeSize it is now possible to enter multiple paths at the same time by separating them using semicolons. Each of these paths may contain wildcards. Example:  d:\data\;e:\logfiles\;h:\user*\

Top 100 List: Added columns Creation Date (by default visible), Attributes, Version, Permissions (by default not visible)

Added column "Full User Name" (by default visible) and "User Comment" (by default not visible) on the "Users" page. Use the column header context menu to adjust columns.

The "Printed Report" and the lists printed using the "Print" button above the "Details" list now also contain the icons.

Added possibility to export a subbranch of the scanned file system to the right click menu of every folder.

Under "Tools > Options > Columns / Export" there is a new export type for CSV files now. This way CSV files can now be configured independently from the text export.

You can now export the user settings to a file ("Tools > Options > Miscellaneous > Settings") and import them later, or provide them to another instance or user of TreeSize. You can also reset the user settings to the factory settings here.

The drive list is no longer blocking TreeSize on startup for a while if an unreachable network path is included in the list.

Introduced new menu "Edit" to the main menu. It provides similar features like the Windows Explorer "Edit" menu and includes: "Cut", "Copy", "Paste", "Select All" and "Invert Selection".

F5 now only updates the "Details" list if the Details list is focused. Otherwise it will, like before, perform a rescan of the currently selected directory branch.

Improved progress dialogs when printing or exporting. They showed a wrong progress sometimes.

Added new command line option /OPTIONS to pass formerly exported user settings to the application. (Professional edition only)

The new command line switch /APPENDTOFILES will make TreeSize to always append its output to existing files when exporting a list in text format. (Professional edition only)

In file names passed on the command line, e.g. for the Excel or XML export, now environment variables can be used. (Professional edition only)

Charts: The colors assigned to the chart are now memorized for the next start. The context menu of the chart has an option to reset the colors to their default values.

Charts: The bar and pie charts now also display Unicode characters.

Charts: All charts can now be copied, saved or printed through their right click menu.

Charts: Introduced new buttons in the toolbar of the "History" and "Age of Files" tab to (de)activate the gradient, patterns and hint marks.

Charts: In the right click menu of the pie chart you can now define the threshold for items to be merged in the "Others" slice.

Charts: You can now zoom the active chart by using the mouse wheel while the "Ctrl" key is pressed.

Charts: Saving to a PNG file is now supported.

Charts: You can now scroll the treemap by keeping the space bar pressed while dragging the treemap using the left mouse button, similar to imaging software (e.g. Photoshop).

A new feature "Manage Scheduled Tasks" has been added to the "Tools" menu of the main application and the File Search. It allows to edit or manage previously created TreeSize tasks. (Professional edition only)

Schedule TreeSize Tasks: Added "Execute this Task" to the right click menu of the "All Tasks" list and the box showing the current command line. (Professional edition only)

Schedule TreeSize Tasks: Added the new functions "Activate Task" and "Deactivate Task" to the context menu of the "All Tasks" page. This state is now also shown by the icon of each task in the list. (Professional edition only)

File Search: Use the new option "Tools > Schedule Current Search Options" to open the TreeSize Schedule Task dialog with the currently configured search settings. (Professional edition only)

File Search - Duplicate Files Search: Introduced new "Deduplicate Checked" button on the right side of the file search window. This button replaces all checked duplicates with links to the same file. If the files are on the same partition, then all files will be hardlinks to the same content. If creation of a hardlink is not possible, a symbolic link is used under Windows Vista and later. If this is not possible too, a Windows shortcut will be created instead as fallback.

File Search: Added column "Author" to the result lists which shows the author included in most MS Office files.

File Search - Move Checked Files: We enhanced the option "Leave shortcut at original location", so that you can now decide to leave a (hard) link instead of a Windows shortcut.

File Search - Move Checked Files: Introduced new option "Automatically rename existing files". If this option is activated, files will be automatically renamed if a file with the same name already exists in the destination.

File Search - Move Checked Files: We introduced a new option "Preserve directory structure". This option is activated by default, because the directory structure was preserved in former versions of TreeSize. You can now deactivate this option to move files directly to the chosen destination. Existing files located in the destination will be renamed (e.g.: "..\" -> "..\") if the option "Automatically rename existing files" is activated.

File Search - Move Checked Files: When moving files from one drive to another, the creation date is now preserved.

File Search - Custom Search: You can now search for folders by checking the "Directory" attribute on the "Size/Attributes" tab.

File Search - Custom Search: You can now search for files and folders having the attribute for Reparse Points / Mountpoints set.

File Search: The command line options  /SIZEUNIT and /NOUNITS are now also supported in the File Search. (Professional edition only)

File Search: The /FILTER command line option no longer sets the patterns for the temporary file search, it now sets the patterns of the custom file search and allows an easy file search for certain file types or patterns. (Professional edition only)

Bugfix: In the right click menu the "Open" command for folders ("Open containing folder" for files) did not work on 64Bit Windows systems.

Bugfix: File Search: When using the "Move Checked Files" function in combination with the "Preserve permissions of the original file" option, in rare cases an error could occur.

Bugfix: When editing the scheduled time or day or trigger type (once, daily, weekly) of an existing task in the "Schedule TreeSize Task" dialog ("Tools > Schedule TreeSize Task"), this change was not stored.

Bugfix: The command line option /TREEMAP was not working in combination with /NOGUI.

Bugfix: When terminating a duplicate file search with MD5 checksums before it was finished, the result list could incorrectly include some entries that were not checked for equal file content.

Many further enhancements and a few minor bug fixes have been incorporated.

Changes in V5.2.3  (31 Mar 2009)

The command line parameters /USERSLIST, /EXTENSIONSLIST and /TOPFILESLIST now support writing to Excel files.

File Search: While calculating MD5 checksums, the duplicate file search now shows the number of remaining files in the status bar.

File Search: The "Duplicate Files" result list now shows the number of files and their summarized size in the status bar, and no longer the number and size of file groups.

File Search: If more than one file is selected, the number and size of the selected files is shown in the status bar.

Bugfix: File Search: The duplicate file search occasionally locked when identifying duplicate files using MD5 checksums.

Bugfix: File Search: A problem has been fixed when using the "Move Checked" function for complete folders that were moved to a ZIP-File.

Bugfix: If a user defined cluster size was reverted to "Original" in the "Options" dialog, this was not applied to current scans even if a rescan was performed.

Bugfix: A problem with the view of the bar chart when it was displaying many folders has been fixed.

A few minor bug fixes and improvements have been incorporated.

Changes in V5.2.2  (17 Feb 2009)

Now the shadow of the pie chart is deactivated as well if the gradient in the background of the chart is deactivated

Bugfix: The total and free space was no longer shown for UNC paths in the drive list.

Bugfix: The file extensions and users statistics was no longer working for virtual root folders

Bugfix: If a single file was dragged from the "Details" list to the directory tree, an error could occur.

Bugfix: When scrolling in the bar chart that had a lot of elements, the chart was corrupted.

Bugfix: On systems that had the Windows printer spooler service not running an error message occurred at the startup of TreeSize.

Bugfix: Deactivating the statistics for "Age of Files" in the Options dialog did not persist when TreeSize was started again.

Bugfix: The option "Include only files created in the past XX days" did also check the creation date of folders in V5.2 and therefore returned unexpected results.

A few minor bug fixes and improvements have been incorporated

Changes in V5.2  (04 Feb 2009)

File Search: The "Move Checked Files" feature is now able to handle paths of more than 255 characters and optionally is able to preserve the permissions of the moved files.

File Search: The "Move Checked Files" feature as well as the /MOVETO command line option (Professional Edition only) now allow to pass the checked files to any executable file as parameter. This offers system administrators a lot of possibilities to manually and automatically process the search results of a TreeSize File Search.

File Search: The search results can now be saved to a native Excel file. If multiple result lists are saved, each list will be placed on a separate sheet.

File Search: With a new option on the "Move Checked Files" dialog you can now automatically remove empty parent directories that are left over after moving / deleting the checked files.

File Search: In the list of search patterns of the "Custom Search" type it is now possible to use patterns that include fragments of a path, e.g.: "C:\Windows\*\*.exe" or "*\Temp\*.old"

File Search: The ZIP files created by the "Move Checked Files" feature are now able to store Unicode file and folder names in the ZIP file. ZIP files containing Unicode paths can only be unzipped properly by Unicode compatible ZIP tools like WinRar or WinZip.

File Search: It is now also possible to start the File Search with Full administrative privileges from the Windows "Start" menu and the "Tools" menu of TreeSize.

File Search: In the "File" menu it is now possible to print a result list or to copy its contents to the clipboard. Use the right click menu of the lists to copy only the selected items.

File Search: It is now possible to copy the contents of the drive list to the clipboard using its right click menu.

File Search: The /DATE command line parameter is now also supported for the file search. This way you can automatically add the current date and time to file names specified for the /TEXT parameter or the /MOVETO parameter with a ZIP file. /DATE will change all file names that appear after its occurrence on the command line.

The new command line options /NOHEADERS and /NOUNITS allow to omit the headers and units from exported files, which simplifies getting plain data for later postprocessing.

A new option allows to exclude files that are marked as Offline. Offline files are often not physically present on the disk or are only cached temporarily on the local disk.

The new command line option /LISTSEPARATOR allows to define the separator that is used when exporting text files.

The new command line parameter /EXPORTDRIVELIST has been added, which saves the contents of the drive list to a file.

Now the Excel 2007 format (file extension XLSX) is supported by TreeSize Professional. This enables you to export Excel files with more than 65,000 rows.

All Excel files saved by TreeSize now have numbers and units separated, which simplifies performing calculations with size values. When saving the "Details" list to an Excel file now only the selected items will be saved if more than one item is selected.

All pattern editors (e.g. View > Options > Include/Exclude, the custom file search, etc.) now have checkboxes in front of their patterns. This allows to deactivate certain patterns temporarily without the need to delete them.

You can now choose to install the Professional Edition as portable version, e.g. on an USB stick. The settings are stored in the application path in this case.

TreeSize now stores the user settings in an XML file in the user's profile.

Treemap: Added OLE drag support to the treemap chart. Drop support will follow in the next version. This allows dragging folders from the treemap to other locations.

Treemap: Ctrl + und Ctrl - can now be used to zoom the treemap. The cursor keys, Home, End, PgUp and PgDown can be used to scroll the zoomed chart.

Added a context menu item that allows to copy the underlying data from the "Age of Files" chart to the clipboard as text.

Ctrl+X now executes the Windows Explorer "Cut" operation in the directory tree and the "Details" list. The keyboard shortcut for "Automatic Units" has been reassigned to Ctrl+U.

When saving a scan to an XML file, the XML stylesheet is now copied next to the exported XML file and is referenced using a relative path. This simplifies using the XML files on systems not having TreeSize installed.

Several minor improvements and bugfixes on the treemap, the bar and the pie charts.

The memory consumption for storing the file types and the user statistics has been reduced.

Bugfix: In the "Duplicate Files" search, when checking all selected items using the context menu (if file group items get selected as well) the check state of the group items was set too, which resulted in an error when using the "Move Checked Files" function.

Bugfix: Fixed a memory leak that occurred on Windows Vista when scanning with the option "Track NTFS Alternate Data Streams and Hardlinks" activated.

Bugfix: It is now also possible to pass domains and servers like \\domain or \\server at the command line. Previously this worked in the user interface but caused an error message at the command line.

Many further enhancements and a few minor bug fixes have been incorporated.

Changes in V5.1.2  (21 Jul 2008)

All lists now provide a new button in their toolbar that allows to save their contents to an Excel file.

Added possibility to export the tree map and the file ages chart in the "Schedule TreeSize Task" dialog.
Here a new function "Save to Batch File" has also been added to the context menu of the text field containing the full command line.

Retrieving the file version of EXE, DLL and similar binary files no longer changes their last access date.

The context sensitive help via F1 key now also works correctly under Windows Vista.

File Search: It is now possible to search for files whose path is longer than a certain number of characters.
This allows to find paths longer than 255 characters which make problems e.g. in the Windows Explorer.

File Search: A selected "Since" interval on the "Date" tab of the Custom File Search is now saved for the next start and to XML files (File > Save Search Options). Previously it was only saved implicitly as lower and upper border of the date interval.

Bugfix: The "Since" date intervals were not working as expected if the negated date filter "Not Changed", "Not Access" or "Not Created" were selected.

Bugfix: The date picker controls of the Custom File Search did not always report the state of their integrated checkbox correctly. This could lead to files missing in the search results.

Changes in V5.1.1  (10 Apr 2008)

TreeSize is now able to handle paths with more than 255 characters when searching or scanning the disk.

TreeSize now applies NTFS compression and removes it from files that are marked as readonly.

The compatibility with 64Bit systems has been improved.

The treemap chart is drawn much faster now for large file system trees.

File Search: When saving a result list, now the visibility and order of the columns is taken into account.

File Search: When performing a move operation with the option "Create Shortcut ..." activated, now a description is added to each shortcut that contains the destination path, the responsible user and the date of the move operation.

A few minor improvements and bug fixes have been incorporated

Changes in V5.1  (04 Mar 2008)

Many improvements for the new tree map:
- If a folder has no subfolders and file extensions statistics was activated during the scan, the file types are now shown as subitems in the tree map.
- Some graphical changes result in an improved appearance of the hierarchy.
- A legend for the colors has been added.
- It is now possible to zoom and scroll the chart in order to see more details.

Improvements in multithreading makes scans up to two times faster.

The Explorer context menu is now available as a submenu in the charts and the root folder of a scan.

When exporting the data to a file, the save dialog now has a checkbox that lets you decide whether or not the file should be opened after saving.

When saving the extensions statistics to a text file, you now have a checkbox in the save dialog that allows you to save the expanded groups only, just as you see it on the screen.

The users and extensions statistics now allow to select multiple items, which is useful if you want to export / print them partially only.

The context sensitive help has been improved. Pressing F1 should now always lead to the correct chapter in the help file.

A new column has been added that shows the error message if a folder could not be scanned. This is useful in particular for scheduled scan that export their results to an Excel, HTML or Text File (Professional Edition only)

If the Mixed Mode for sizes is turned on, the charts will now also use an appropriate size unit for displaying size values.

It is now possible to delete single values from the history chart using the right click menu.

Some other minor bug fixes and improvements have been incorporated.

File Search:

Added new columns to the result lists that show the attributes of the files, the version number of binary files, the permissions and the creation date. Some of the new columns are by default turned off and can be turned on using the "View" menu.

The "Move To" dialog of the File Search now has an option to create shortcuts for moved files at their original location that point to their new location.

Added possibility to search for files with NTFS alternate data streams in the custom file search (tab "Attributes"). If this search is active and alternate data streams are found, their sizes are added to the file size and in the column "Attributes" a "*" is added to the attributes. Checking for alternate data streams is slow and requires read access to the files that should be checked.

Changes in V5.0  (23 Nov 2007)

It is now possible to group scans under a virtual root folder. This virtual root folder shows a summary of all scans that are part of this group. This way you can merge different scans together e.g. for printing or exporting. You can access this feature through the context menu of a root folder or through the "Tools" menu.

A new kind of chart called "Tree Map" has been added. It shows a hierarchical view of the file system. In this treemap chart each folder is shown as a rectangle with its subfolders inside, again as rectangles.

The list on the "Extensions" tab can now be grouped by file types like "Audio Files", "Video Files", "System Files", etc. This feature can be turned on or off by a new toolbar button.

The tabs "Extensions", "Users" and "File Ages" now have a feature "List Files" that generates a list of files of the selected item.

The selected items in the various file and directory lists of TreeSize now show the selection using a style similar to Windows Vista. This makes colored text and the small embedded charts easier to read.

The TreeSize column for the Windows Explorer is now also supported on 64Bit systems. The .NET Framework 2.0 is required on 64Bit systems for the column to work. Unfortunately a Microsoft employee confirmed that such an additional Explorer column won't be possible under Windows Vista.

The number of decimals can now be set in the View menu instead of the "Options" dialog.

The gradient colors of the optional indicator bars in the tree can now be chosen in the "Options" dialog.

In the Options dialog you can now change the maximum number of threads that TreeSize creates for each scan. Like before TreeSize will still adjust the number of threads to the current system load and so often create less threads than the maximum number.

In the Options it is now possible to customize the intervals that are used to generate the chart on the "File Ages" tab.

TreeSize has a new option that allows taking hard links and alternate data streams into account when calculating disk space, which produces more accurate results. However this makes it necessary to open the files and therefore slows down a scan.

The "View" menu now allows switching to plain Byte values.

The Excel, Text and HTML export options now allow to specify whether or not units like "KB", "MB" or "%" should be added to exported values. By omitting units the thousands separators will also be omitted, which simplifies further processing of exported values. This replaces the former option File / Export / Use plain numbers.

The command line options /FILEAGESCHART and /HISTORYCHART have been added. They allow to save the charts on the "History" and the "File Ages" chart.

The new command line option /TOPFILESLIST allows exporting the top 100 files list.

The columns of the "Copy list of files" feature are now determined by the settings for the "Text Export" in the "Options" dialog of TreeSize

The executable has been renamed to "TreeSize.exe".

The support for Windows 98 and ME has been dropped. Registered customers are still able to download the Windows 98/ME compatible TreeSize V4 from our customers area.

New application icon.

File Search:

An additional search type "Custom Search" has been added. This search type allows you to freely define and combine search criteria like file name, date, size, attributes and owner. The results can be printed or exported like you are used from the other available search types.

Now entire servers, entire domains or even your entire network can be searched. TreeSize automatically browses for PCs and all shares on them (including hidden shares) and performs the search on all shares that it finds.

Improved multithreading support, especially for the MD5 checksum calculation, which should produce results faster on multi-core machines.

It is now possible to export and import the results as simple paths only (DIR /B /S format). This simplifies post-processing of TreeSize results and allows to import lists of paths in TreeSize.

It is now possible to pass an XML file to the TreeSize File Search on the command line, which contains previously saved search options. This simplifies scheduled scans with predefined search options.

The Move operation now optionally logs the performed operations to a log file.

The result lists do now work as a source for drag and drop operations.

A new feature "Check all but Newest" has been added to the context menu of the duplicate file search results.

A new feature in the context menu of the duplicate file search allows to replace duplicate files with hard links. This way all the duplicate files remain at their position, but only one file occupies disk space.
