WizTree

WizTreeMac (macOS) vs WizTree (Windows)
WizTree 4.33 (16 September 2026)
WizTree is now available for macOS 12 or later and is called "WizTreeMac".
WizTreeMac 1.00 includes most of the functionality in WizTree 4.33 - See here for more info
Updated to support import/export of CSV files generated by WizTreeMac
MacOs allows double quotes in file names and these are "escaped" as 2 repeated double quote chars, e.g. file name
Say "Hello".txt
will be written to the CSV file as
"Say ""Hello"".txt"
This version can also handle the macOS root folder "/" correctly when importing
Startup screen will now display a "ready to scan" message along with some explanatory text about using the app, along with
license information if the application has any.
Missing translation items (if any) have been updated for all languages
Copy/Cut was not working in the text box when renaming a file - fixed

WizTree 4.32 (5 August 2026)
Windows Arm support: WizTree is now officially confirmed to work on Windows Arm devices via Prism Emulation
WizTree will now detect if it's importing a "complete" CSV file and will allow filters to be applied with recalculation enabled.
Previously WizTree would not recalculate any values when filtering an imported CSV and just display the total values from the CSV file.
The reason for this is that it's possible to export incomplete CSV files (e.g. folders only), so recalculating folder sizes would
result in invalid values being displayed due to the missing file information.
Fixed bug with date filters not working as expected (introduced in 4.27 when filtering by time was added)
ReactOS: WizTree will now default to "classic" theme if ReactOS detected
WizTree will now auto convert Linux forward slash "/" to back slash "\" when importing CSV files generated using Linux paths
Entering in a new supporter code while running in non-admin mode on the installed version would fail silently due to insufficient rights -
WizTree will now pop up a message requesting to be restarted with admin rights in this situation
WizTree will now correctly work with dotted command line parameters, like "." or ".." or "..\XXX" etc - these will be expanded
to the full directory name
e.g. to scan the current folder when running WizTree from the command prompt:WizTree64 .
Turkish/Thai translations were mixed up in the installer - fixed
Fix for "Exception ETaskbarException ... Could not initialize taskbar" error that could occur on Windows Server Core versions

WizTree 4.31 (23 March 2026)

Cancelling a rename operation would prevent files from being opened - fixed
Double clicking a file would not open it on Windows XP - fixed

currently selected file within WizTree. Press space again to close the view.

or use am/pm like this:

Example 2: To find files modified at 3am or earlier (any day):
<=3am
Use the "NOW" filter variable for the current date/time.
Example 3: To find files modified in the last 5 minutes, use filter:
>NOW-5

CSV Export options that were previously only available via command line
are now selectable when using the Export to CSV function.
Additional data items can be included in the export along with extra filtering and sorting options.
Note that either "Tree View" or "File View" data will be exported depending on which tab is active. Select the correct tab before
selecting the CSV export function.
CSV file exports will now include drive size info by default (total space, space used, space free and reserved space). To exclude this info from the exported CSV file, set command line parameter /exportdrivecapacity=0
CSV files containing drive size info will have the info displayed on screen (previously only space used was displayed when importing a CSV file)
CSV file import speed greatly increased

WizTree 4.24 (31 January 2025)
WizTree will now hide drives hidden by Windows Group Policy settings (if any). Note that these hidden drives can still be selected by
using 'Select Folder' and then typing in the drive name, e.g. "c:" (like Windows Explorer allows)
percentage displayed for file extensions was not calculated correctly when multiple items were scanned together - fixed
Percentages displayed will now always default to being calculated using "allocated" values instead of "size", unless sort order is set to "Size"
as "Allocated" is the default sort order
Duplicate detection method now defaults to name, size AND date (previously just name and size) - will affect new installs only
it's now possible to set the WizTree config folder location via command line parameter. e.g. /configfolder="c:\WizTreeConfig"
OR by creating the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Antibody Software\WizTree
