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
