What's New in WizTree?

WizTree Change Log

WizTree 4.19 (5 March 2024)

WizTree now offers the ability to find duplicate files based on Name and Size, or Name, Size, and Date. It treats file names automatically renamed by Windows as equivalent, such as “NAME.EXT,” “NAME (1).EXT,” “NAME (2).EXT,” “NAME – COPY.EXT,” and “NAME – COPY (1).EXT.” Please note that WizTree does not currently compare file contents, so exercise caution before deleting files that may not be true duplicates.

To find duplicates, navigate to “File View” and choose the duplicate detection method from the “Duplicate Files” drop-down menu. Any duplicates found during scanning will be marked with a “+” symbol beside the file name. Click on the plus sign to expand the list of duplicate files, which will be shown beneath the original file.

Once duplicates are identified, new columns labeled “Dup Count” (indicating the number of duplicates for each file) and “Dup Size” (representing the total size of all other duplicate files) will be visible. These columns allow for easy sorting to quickly locate duplicates. Simply click on the column headers to sort the list based on these criteria. To streamline the display and focus solely on files with duplicates, check the “Duplicates only” checkbox.

In the “File View,” a new standalone “File Name” column now exclusively displays filenames, excluding the path.
An issue has been resolved where the File View might not have displayed all relevant files unless “max files” was set to “ALL” and sorting was by size.
File View sorting processes have been significantly accelerated for enhanced efficiency.
Regular expression filters will no longer erroneously apply to the “entire path” when “name only” matching is selected, particularly if the regex contains a backslash.
Themes will now automatically deactivate when WizTree runs as the local system account (“SYSTEM”), addressing display issues that arose when utilizing remote access tools like ScreenConnect.
Stability enhancements have been implemented for scanning network folders and drives, ensuring smoother operations.

WizTree 4.18 (2 February 2024)

The “Include” filter is now deferred until after scanning to prevent incorrect filtering of files and folders during the process. Only the “Exclude” filter is applied during scanning.
Enhanced processing of the “=folder” filter enables the location of folders based on specific size criteria. For instance, using a filter like “=folder >1g” now identifies folders larger than 1 Gigabyte.
Resolved a bug in allocated size filtering where file size was incorrectly used instead of allocated size. For instance, “a>100m” now correctly filters files by allocated size larger than 100 Megabytes.
Operations such as Copy, Cut, and Delete now function correctly when multiple files from different folders are selected. Previously, they only worked when all files were in the same folder.
The progress bar has been refined for smoother performance.
Addressed an issue where progress was not displayed when loading CSV files, ensuring accurate progress updates on the screen.

WizTree 4.17 (22 January 2024)

“While scanning non-NTFS drives such as folders, network shares, and mobile phones, both “Include” and “Exclude” filters are now applied. This optimization can significantly accelerate scans by preventing certain folders from being scanned altogether, thus reducing memory usage. This feature also extends to exports via the command line.

To toggle filters on or off, simply click on the filter button located under the Scan button, or navigate to Options -> Filter Scan Results (Ctrl+Shift+F).

For instance, if you’re using a Synology NAS, you can instruct WizTree to disregard snapshot and recycle folders by configuring the “exclude filter” as follows: #snapshot|#recycle|@recycle before initiating a scan. Note that there should be no spaces between the vertical pipes (interpreted as “OR”), and spaces are interpreted as “AND.” The provided example will exclude any file or folder name containing “#snapshot,” “#recycle,” or “@recycle”.”

For instance, to exclude the “C:\Windows\WinSxS” and “C:\Program Files” folders from scanning, configure the exclude filter as follows: C:\Windows\WinSxS|”C:\Program Files”. Please note that double quotes are necessary around filter items containing spaces.

Resolved the issue where exploring a folder containing an executable with the same name as the folder would launch the executable instead of opening the folder.
WizTree now automatically removes any spaces between vertical pipes in filter and search fields to ensure they function correctly.
Updated Slovak, Turkish, and Swedish translations for enhanced language support.

WizTree 4.16 (13 November 2023)

Drag and drop functionality can now be easily enabled or disabled based on user preference.
Option to enable or disable opening files on double-click has been added for enhanced customization.
Users can now choose to enable or disable file system monitoring, which affects WizTree’s ability to detect deleted files and folders.
The display of the maximum modified date can toggle between showing the maximum date of all subfolders and files or the last modified date of the folder itself.
Users have the option to enable or disable the WizTree classic theme. Some users report that enabling the classic theme enhances the UI’s responsiveness.
Horizontal lines in the grid view can be enabled or disabled as per user preference.
Users can choose to enable or disable alternate row colors for grids.
The option to enable or disable gradient colors in the treemap has been added.
Users can specify the number of decimal places as needed for precision.
When selecting files, the total allocated size of the selected items is now displayed alongside the total file size for improved clarity.
The sorted column will now be highlighted, enhancing visibility and usability.
Addressed a rare issue where WizTree would occasionally inaccurately flag files as deleted when scanning very large drives.
Refined the appearance of file and folder icons in tree and file views to ensure they look better when scaled.
Fixed an issue where Unicode characters were not being correctly saved to the search and filter drop-down history.
Emojis are now displayed correctly in file search and filter fields, resolving a previous display issue.
Mobile phone scanning code has been optimized to be more robust. It should now successfully scan phones that previously failed to scan.

WizTree 4.15 (14 August 2023)

The UI has been adjusted to resemble the Windows 11 style, offering a more modern look and feel.
WizTree now supports exporting/importing “.tsv” (tab-separated values) files. Simply set the file name extension to “.tsv” when saving to enable this feature; otherwise, it will use a comma to separate the values.
Fixed an issue where some UI elements appeared slightly blurry on high DPI screens, ensuring a clearer display.
Deleted files will now be highlighted with a red outline in the treemap as soon as they are detected, aiding in their identification.
Addressed a treemap hover glitch that could occur in certain situations when deleting files, ensuring a smoother user experience.
Various translations have been updated for improved language support and accuracy.

WizTree 4.14.0.1 (6 June 2023)

Apologies for any inconvenience caused. A row height scaling issue with high DPI screens has been addressed and fixed. If you downloaded version 4.14 (released on 5 June 2023), please download it again and reinstall to ensure the issue is resolved.

WizTree 4.14 (5 June 2023)

Addressed a rare bug that could prevent WizTree from detecting some folders due to unusual MFT record ordering when parsing the MFT file.
Users can now adjust the text size in Tree, File, and Extension views by using Ctrl+MouseWheel to increase or decrease the size.
When importing CSV files, WizTree will now display the line number containing invalid data that caused the import to fail, aiding users in troubleshooting.
Introduced a new “Reset Configuration to Default Values” function in the File menu, which restores all settings (except licensing info) to default values. Useful for resolving any issues like abnormal column widths or font sizes.
By default, WizTree will now display the maximum “last modified date” for all files and folders within a folder instead of the standard Windows last modified date. To disable this, users can edit the
WizTree3.ini file and change the setting “ShowMaxModifiedDate=0”.
WizTree will now default to sorting by “Allocated” space instead of “Size” as it better reflects the actual space used by files. Allocated space will also be displayed on the
Treemap by default. These changes apply to new installations or when resetting the configuration.
The installer has been updated to use the correct configuration file location when installed to a non-“Program Files” location. This ensures that configuration parameters are applied correctly, especially for Enterprise users running automated installs as the “SYSTEM” user.
The installer will now update the registry to make mapped network drives created by non-elevated processes visible to elevated processes like
WizTree, improving accessibility. Note that a restart may be required for this change to take effect if not already enabled.

WizTree 4.13 (15 March 2023)

Regular Expression search functionality has been implemented. To perform a regex search, type a forward slash followed immediately by the regex pattern. For example: /[0-9]{4}-[0-9]{2}-[0-9].csv$. If the regex contains spaces, enclose it in double quotes.
Regular expression searches can be utilized for file search and include/exclude filters.
A search history dropdown has been added to File Search and Include/Exclude filters for improved usability.
Include/Exclude Filters can now be applied to the entire path (default) or file name only.
A new command line parameter /filterfullpath=[0|1] has been added to control whether filters are applied to the full path or file name only. The default is the full path.
Support for DrivePool, Storage Spaces, and similar “virtual” drives has been added, addressing previous issues where WizTree would crash or stop working when scanning these types of drives.
Fixed an issue where importing a CSV file would display incorrect file dates/times due to a timezone adjustment error.
Resolved a possible “Access Violation” error on startup when scanning for devices such as mobile phones.
Default sorting can now be set via the command line using /sortby=sortoption, where sortoption can be:
1 = sort by file size (descending), file name
2 = sort by allocated size (descending), file name
3 = sort by modified date (descending)
Percent of Drive calculations (File View) are now accurate even when multiple drives are selected.
WizTree will now remember if tree and file view data is being sorted by size or allocated and will use the same sort order when restarted.
Added a new Indonesian translation (thanks to Marcellinus Ferdinand Sucia).

WizTree 4.12 (1 December 2022)

Addressed an issue with file size filters (e.g., >1g) not handling folders correctly, ensuring accurate filtering.
Resolved a file filter bug that could cause matching files not to appear in certain cases, ensuring consistent results.
Added a new Czech translation (thanks to Masterix) for expanded language support.

WizTree 4.11 (26 October 2022)

Corrected an issue where the “Today” file search filter (=today) was not functioning correctly in certain time zones, ensuring accurate search results.
Command line parameters for /filter and /filterexclude now support literal double quotes, which is particularly useful for filtering paths containing spaces. To represent the double quote, use a single quote character within the command. For example:

This command would set the “include filter” to “C:\Program Files”|”C:\Program Files (x86)”. Two single quotes in a row will be treated as one literal single quote.
Resolved a crash issue in WizTree 4.09/4.10 that occurred when running as the “SYSTEM” user (“NT AUTHORITY\SYSTEM”) due to conflicts with the newly added drag/drop functionality.
Fixed some cosmetic issues with the Italian translation for improved visual consistency.

WizTree 4.10 (29 August 2022)

Resolved an issue where the Treemap would not render correctly when the “show free space” option was not selected in certain cases, such as with mapped Google Drives or when scanning a mobile phone.
Users can now disable the drag/drop and double-click to open functionality added in version 4.09. To do this, close WizTree and edit the
WizTree3.ini file, changing the following settings in the [frmWizTreeMain] section:
Fixed a rare command line export error that occurred when using the “/exportalldates” parameter.
Resolved an error that would occur when using the “save Treemap as PNG file” option with multiple selections and “show free space” enabled.
Updated Korean, Serbian, and Polish translations for improved accuracy and consistency.

WizTree 4.09 (15 August 2022)

Disk free space on the Treemap will now be displayed separately for each selection when using the “select multiple” option, providing clearer visibility.
Export functions have been updated to consistently format floating-point values (like percentages) using a period as the decimal separator. This ensures compatibility when importing data into other applications, especially spreadsheets.
Double-clicking a file or folder in the tree or file view will now automatically open it, streamlining navigation.
Files/folders can now be dragged out of WizTree and into Windows Explorer windows to copy/move them. Hold the Ctrl key while dragging to copy the file; otherwise, it will be moved. Dragging will only work when initiated from the file name column. Dragging in other columns will select all files in the selection rectangle.
“Copy” (Ctrl+C) and “Cut” (Ctrl+X) menu items have been added to the File menu. The shortcut for copying the path has been changed from Ctrl+C to Ctrl+Alt+C.
The “Copy Path” function will no longer include a trailing carriage return if only one item is selected, improving usability.
The drive name is now displayed in the tree view and Treemap, enhancing clarity.
Menu accelerator keys now function correctly in dark mode.
A new command line parameter has been added to select size or allocated space for Treemap image export. The default is size.

WizTree 4.08 (14 February 2022)

A new “Filter Scan Results” option has been added, allowing users to filter entire scan results using a user-defined filter.
The filter can be toggled on or off by clicking on the filter icon under the Scan button, selecting Options->Filter Scan Results, or pressing Ctrl+Shift+F.
The “Include Filter” includes only matching files in the results, while the “Exclude Filter” excludes any matching files from the results.
Users can click on the “Apply Filter” button (or press Enter after making a filter change) to apply any filter changes made. Files are matched using the entire file path and file name. The filters support all standard file search functionality, such as wildcards, file size, and file date.
For example, to filter only files of type mp3 or wav, larger than 5MB, excluding anything in the C:\Windows folder, you would enter:
Include Filter: .mp3|.wav >5m
Exclude Filter: C:\Windows\
Fixed an issue where wildcard search for file extensions was not working correctly when the “match entire path” option was used. For example, searching for *.c would include files including “.c” anywhere in the file name, which would include *.cpp or *.c.bak files too.
The Total space, space used, and space free display fields have been widened to correctly display very large TB drive values when displaying as Bytes.
Fixed an issue where the window position was not being restored to the correct position if the Windows taskbar was not positioned at the bottom of the screen.
Resolved some dark mode display issues on older versions of Windows (2003, XP) for improved visual consistency.

WizTree 4.07 (6 December 2021)

File name search will now ignore character accents (like é and ö) when searching. For example, searching for “melee” will correctly match file names containing “mêlée” or “MÊLÉE”.
WizTree now correctly handles MTP/PTP devices that do not provide a “friendly name”, ensuring smooth functionality.
Resolved an issue where MFT dump would fail on Windows XP, ensuring compatibility with older systems.
Removable USB devices formatted with NTFS will now be detected for high-speed scanning and allow MFT dump, addressing a previous limitation.
WizTree now checks if Windows Imaging Component is installed before starting up. This component is required for Windows 2003 and possibly some versions of XP.

WizTree 4.06 (19 November 2021)

File size information will now also be displayed on the Treemap if the “show files and names in Treemap” option is enabled, enhancing data visibility.
WizTree will now function correctly on older versions of Windows like Windows XP, addressing previous incorrect fixes implemented in version 4.05.
The Treemap image can now be exported via the command line using the following parameters:
Set image file name (use %d and %t for current date and time in the file name): /treemapimagefile=<png image file name>
Set image width (default is 1920 if omitted): /treemapimagewidth=<image width (numeric)>
Set image height (default is 1080 if omitted): /treemapimageheight=<image height (numeric)>
Export image in grayscale. Defaults to 0 if omitted: /treemapimagegray=0|1
Show free space on Treemap. Defaults to 1 if omitted: /treemapimagefreespace=0|1

WizTree 4.05 (17 November 2021)

WizTree 4.04 has resolved error messages occurring on PCs lacking MTP support, such as older versions of Windows XP. Additionally, the issue where toggling off Windows Explorer integration didn’t entirely remove WizTree from context menus has been fixed. Furthermore, title bar display problems on very high DPI screens, where the maximize/minimize buttons were too small, have been addressed. Notably, the WizTree installer now supports optional command line parameters. Users can set the supporter code license on installation using “/supportercode=xxxx-xxxx-xxxx-xxxx”. Moreover, the option to set “always run as admin” can be configured with “/runasadmin=TRUE|FALSE”, and the “check for updates” setting can be adjusted with “/checkforupdates=TRUE|FALSE”. For instance, users can input “wiztree_x_xx_setup.exe /supportercode=1234-5678-abcd-1234 /runasadmin=false /checkforupdates=false”.

WizTree 4.04 (4 November 2021)

WizTree now boasts enhanced functionality, allowing it to scan a variety of portable devices supporting MTP/PTP, such as mobile phones, music players, storage devices, and cameras. For instance, to scan files on your mobile phone, simply connect it to your PC via USB cable. Then, select either “file transfer” or “photo transfer” mode prompted by your phone. Subsequently, your phone will appear in WizTree’s dropdown drive list, enabling you to select it for scanning.

Moreover, the latest update enables the selection of MTP/PTP device folders when utilizing the “select folder” option. Additionally, issues have been resolved, including the status message remaining as “Show Treemap” after drawing treemaps for multiple large drives, malfunctioning of the “Not (!)” operator when followed by quoted search text, and exclusion of some results when using the “?” wildcard for searching the entire path.

Furthermore, improvements have been made to handle right-to-left languages like Arabic correctly in the file search box and highlighted text.

WizTree 4.03 (22 September 2021)

The latest update of WizTree addresses issues related to rendering treemaps on very large hard drives, ensuring their successful display. Additionally, when zooming in on the treemap, the “free space” will now be hidden if the “show free space on treemap” option is enabled, providing a clearer visualization.

Moreover, users can now access a limited context menu when loading CSV or MFT files from other PCs. Previously, no context menu would appear if the file or folder didn’t exist locally. This enhancement enhances usability and functionality, facilitating smoother interactions with files from external sources.

WizTree 4.02 (20 September 2021)

WizTree introduces several enhancements to its treemap feature. Now, the treemap displays both file and folder names for large files and folders. You can double-click on a folder or file in the treemap to zoom into that specific location. Convenient navigation buttons like “..” and “” allow for easy unzooming or resetting the treemap to the root. Alternatively, users can access “Zoom in Treemap” and “Zoom out Treemap” options from the file or folder context menu.
Moreover, users can toggle the display of file and folder names in the treemap via “Options->Show File and Folder Names in Treemap”. The “explore folder” option now automatically selects the file in Windows Explorer if a file was chosen.
New search terms have been added to file search, allowing users to filter by folders or files exclusively using “=folder” or “=folders” and “=file” or “=files” respectively. Additionally, search by file name length (“namelen”) and path length (“pathlen”) is now possible.
For advanced users, new export command line parameters offer more flexibility. To export “percent of parent” data, include “/exportpercentofparent=1”. Setting the maximum folder depth to be exported is achievable by including “/exportmaxdepth=n” (where “n” represents the maximum folder depth). For instance, “/exportmaxdepth=1” exports only the root folders and files, while a max depth of 0 means unlimited (default).
Lastly, the gradient in the treemap can now be disabled by editing the WizTree3.ini file and setting “GradientEnabled=0”. These updates enhance usability and customization options for a more tailored user experience.

WizTree 4.01 (21 June 2021)

Supporter codes acquired prior to version 4.00 are now “lifetime” licenses, valid for all forthcoming WizTree releases. Issue resolved: certain drive types failing to show total and free space. Enhanced Treemap context menu now offers diverse configuration options, including displaying treemap, allocated space, and free space. Updated Polish and Turkish translations.

WizTree 4.00 (10 June 2021)

Enhance your file scanning efficiency by selecting and scanning multiple drives and folders simultaneously using the “Select multiple” option or pressing Alt+F3. Easily include custom folders by clicking the “add folder” button, which will then be accessible from the main drop-down selection box for quick access. The file search functionality now mirrors WizFile’s, offering advanced filter options applicable even when calling WizTree from the command line. Utilize operators like “=”, “>”, “<“, and more to filter files by size or modified date, without spacing between operators and values. For instance, find files less than 100 bytes with “<100”. Size specifications can be in Kb, Mb, Gb, or Tb by appending ‘k’, ‘m’, ‘g’, or ‘t’. Filter by “allocated” size using “a=”, “a>”, etc. For example, to locate files with allocated size between 100MB and 200MB: “a>=100m a<=200m”. Date filtering is also available, e.g., find files modified before 2020/01/01 with “<2020/01/01”. Use “today” as a constant to reference the current date and modify with “+/-” days, like “>=today-7” to find files modified in the last 7 days. File search speed has been boosted, and matching text is now highlighted in results. Note that the WizTree website has moved to “diskanalyzer.com”, and licensing for commercial users now depends on business size, valid for all WizTree versions released within one year of purchase. For instance, a license bought on 1 July 2021 remains valid until 1 July 2022.

WizTree 3.41 (5 May 2021)

Resolved issue introduced in 3.40 preventing correct scanning of mapped network drives.
Fixed incorrect cluster size calculation, ensuring accurate “allocated size” calculations.
Rectified problem where right-clicking on drive letter failed to display context menu.
Addressed inconsistency in calculation of “percent of parent” for individual files grouped within a folder, now accurately displaying the percentage size of each file within the group.

Enabled toggling selections on and off by Ctrl-clicking files in the tree map (previously, Ctrl-clicking did not unselect files).
Added support for very long file names (>260 characters in total).
Resolved scanning failures of network drives in certain cases (e.g., on Parallels desktop for Mac).
Implemented minor cosmetic changes, including fixing label color issue on Windows XP.
Updated Turkish translation (thanks to Ferhat MURAT).
Note: Many WizTree translations are outdated due to original translators’ unavailability. Contact us to update your language translation.

WizTree 3.37 (23 February 2021)

Optimized tree map display drawing, now showing progress only when handling more than 1,000,000 files to enhance speed.
Fixed issue with drive selection box malfunctioning when “display drive letters” option in Windows File Explorer was disabled.
Updated digital signature verification method to prevent unwanted Internet access triggered by the previous Windows API method (WinVerifyTrust) when required digital certificates were not already installed on the PC.

WizTree can now be configured to display the maximum “last modified date” for all files and folders within a folder instead of the standard Windows last modified date. To enable
this feature, edit the WizTree3.ini file and change the following setting: ShowMaxModifiedDate=1. The default setting is off (0). WizTree3.ini is located in %appdata%\WizTree3\WizTree3.ini (for the installed version) or in the same folder as the WizTree exe file for the portable version.
Updated translations for Russian (thanks to Dmitry Yerokhin), Japanese (thanks to maboroshin), and Korean (thanks to Kim YoungCheon).

WizTree 3.33(14 May 2020)

Network and substituted drives previously invisible to WizTree when running as administrator are now selectable. This addresses a Windows bug/feature preventing elevated applications from accessing these drives created by a non-elevated process. In such cases, WizTree will display the contents of network drives using the UNC name (e.g., \servername\sharename) and substituted drives will show the contents of the local folder the drive is mapped to instead of the mapped drive letter.
Added an option to display values in TB. Values larger than 1024GB will be displayed in TB in dynamic value display mode.
Fixed an issue where /filterexclude wouldn’t work unless a /filter was specified.
names are now matched against the filter specification using a trailing backslash to ensure accuracy.
Files without an extension can now be filtered by using “*.” filter, addressing a previous issue where the period was not included in the filename used for matching.
Improved the display of total file and folder info when importing a CSV file exported with folders only (“/exportfiles=0”).
Fixed a bug where importing a CSV file without complete folder information could corrupt file names, impacting the functionality of the context menu.
Resolved an issue where importing a CSV file from a network share (e.g., \servername\sharename) would drop the leading “\”.
Added the ability to set row height in the WizTree3.ini file (“rowheight=xx”). The default is 19, useful for adjusting row height if the font height setting is increased in the file.
When sorting by allocated size, the percentage of parent calculation now uses allocated size values.

WizTree 3.32 (27 January 2020)

Resolved an issue where Windows Explorer integration was not functioning correctly with Windows desktop and in folder backgrounds.
If you had WizTree installed before upgrading to this version, toggle Windows Explorer integration off and on again to fix the problem.
Adding or removing a USB drive will now automatically update the drive list.
Updated various translation files for improved localization.

WizTree 3.31 (22 January 2020)

Added functionality to export file types to a CSV file.
Use the command line option /exportfiletypes=filename to export file type information.
Introducing a new command line option /filterexclude, which functions similarly to /filter but excludes any matching files from being exported.
Implemented a new command line option to set supporter code for Enterprise users: /supportercode=xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xxx
Example: WizTree.exe /supportercode=xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xxx
If there’s an error setting the code, it will be displayed on screen; otherwise, nothing is displayed. This action only needs to be done once per PC.
Resolved a crash occurring when scanning a folder with exactly 9 files.

WizTree 3.30 (31 October 2019)

Introduced the option to purchase a “WizTree Enterprise License” for unlimited use within organizations.
Tweaked treemap drawing to enhance edge distinctiveness.
Added “WizTree” to the internal file context menu, providing convenience when WizTree isn’t configured to be integrated with the Windows Explorer context menu.

WizTree 3.26 (6 September 2018)

Users can now link colors to file extensions by configuring via Options->Colors and setting “Color by” to “Extension”.
Enhanced support for Windows high DPI scaling, addressing issues where fonts would appear excessively large on some PCs when 200% or more scaling was enabled.

WizTree 3.25 (8 July 2018)

Fixed a potential crash issue with the 64-bit version when displaying message dialogs on certain PCs.

WizTree 3.24 (6 July 2018)

WizTree CSV files exported via the “export to CSV” option are now importable and viewable.
Select “<CSV File>” in the selection combo box or press Shift+F3 to choose a CSV file for import.
Enhanced Windows 10 high DPI support, ensuring proper scaling on high DPI monitors.
Fixed a performance issue where resizing the form while the treemap was active would continuously redraw the entire treemap, causing slowdowns.
