What is WizTree?​

WizTree is a very high speed disk space analyzer utility for Windows. It scans your hard drive and shows you which files and folders are using the most disk space. Your entire hard drive's file system is displayed visually, making it very easy to locate large files and folders. Use the information WizTree provides to quickly locate and remove "space hogs" from your hard drive.

WARNING: Take care not to remove any files that are required for the correct operation of your PC!

What makes WizTree so fast?​

When scanning NTFS formatted hard drives (most modern hard drives use this format), WizTree reads the hard drive's Master File Table (MFT) directly from the disk. The MFT is a special hidden file used by the NTFS file system to keep track of all files and folders on a hard drive. Scanning for files this way completely bypasses the operating system (Windows) and provides a huge performance boost.

WizTree can also scan non NTFS hard drives, network drives, USB drives and individual directories.

WizTree 4.20 (29 July 2024)​

• New tweak option added (Options->Tweaks):
  "Scan MFT (if possible) when a folder is selected for analysis" - default is off
  Normally, when a folder is selected for analysis WizTree will scan using the Windows API (MFT scanning is not used). This method is generally quicker when analyzing small to medium sized folders, but for very large folders it can be much quicker to scan the entire MFT file instead.
  If this option is enabled WizTree will always scan the MFT file (is possible) when a folder is selected. You can also force WizTree to scan the MFT when a folder is selected by holding down the CTRL key when starting a new scan. The CTRL key must be down when the scanning process starts for this to work.
• Fixed possible reverse order sorting issue in File View when scanning multiple drives/folders
• Cut/Copy files to clipboard working again on Windows XP/2000/2003 (stopped working in 4.18 due to compatibility issues with new code)
• Processing of folders with millions of files with unique file extensions greatly sped up. Previously WizTree could appear to stop responding when loading such folders into the tree view or when generating the tree map.
• Tree map export now always processes files and folders in size order as the resulting output looks much nicer this way
• Windows Explorer context menu shortcut key for WizTree changed from W to Z (from &WizTree to Wi&zTree) to prevent conflict with "New" option
• Fixed issue where file sizes/allocated sizes could incorrectly be set to 0 for hard linked files in some cases
• MFT scanning speed up to 15% faster in certain cases over previous version

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
  and creating a string named "configfolder" within this key containing the config file folder location.
  The command line parameter will take precedence over the registry key. This setting and command line work with both the installer (setup) and WizTree executables (4.24 or newer)

WizTree 4.25 (28 February 2025)​

• 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
• Fixed bug in 32 bit version that would prevent Windows\System32 folder from being scanned correctly when using slower non NTFS method

WizTree 4.27 (26 August 2025)​

• Seer / QuickLook integration added
  Seer and QuickLook both provide a quick and easy way to preview files by simply pressing the space bar when a file is selected in Windows File Explorer. If you have either Seer or QuickLook active (running in the background), press space to quickly view the contents of the currently selected file within WizTree. Press space again to close the view.
• Filtering/searching by time now supported
  
  Example 1: To find files modified at exactly 1pm (any day):
  =13:00:00
  or use am/pm like this:
  =1:00pm
  
  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
  (find all files with modified date greater than time now minus 5 minutes)
  Use a 's', 'm' (default) or 'h' suffix to indicate seconds, minutes or hours.
  
  Example 4: To find files modified in the last 1 hour:
  >NOW-1h
  
  Example 5: Find files modified more than one hour ago, but less than 4 hours ago:
  <NOW-1h &ht;NOW-4h
  
  Similar results can be achieved by subtracting seconds, minutes or hours from the "TODAY" filter variable:
  >TODAY-5m
  This will show all files modified in the last 5 minutes. Use an 'h', 'm' or 's' suffix to indicate hours, minutes or seconds
• WizTree would incorrectly display "internal corruption detected" error if running from a path containing non ansi characters (e.g. Chinese or Japanese) - fixed
• Config folder override registry setting was not working when WizTree not running in admin mode - fixed
• CSV export can now be configured to export UTC date/times instead of local system date/times. Use command line parameter:
  /exportUTCTime=1
• Setting the license key (supporter code) and configuring auto update checking via the installer will now work for all users on the PC regardless of which user ran the installer. Previously these settings were user specific which could cause confusion
• Fixed allocated size calculation bug that could occur on drives formatted with large cluster sizes
• Most of WizTree's configuration options can now be set via the registry - useful for mass deployments (installed version only)
  Add settings to the HKEY_LOCAL_MACHINE\Software\Antibody Software\WizTree\ConfigOverride\frmWizTreeMain key.
  Setting names should match those used in the WizTree3.ini file and all value types should be of type "REG_SZ" (string).
  e.g. to set the "run as admin" option to false create a "REG_SZ" value named "actRunAsAdmin_Checked" in the
  HKEY_LOCAL_MACHINE\Software\Antibody Software\WizTree\ConfigOverride\frmWizTreeMain registry key and set the value to "FALSE"
  To make a setting "read only", prefix the name in the registry with an exclamation point (!), e.g. !actRunAsAdmin_Checked
  When the installed version of WizTree starts (does not matter which user is logged in), it will first look to the registry and set its settings accordingly. If WizTree is being run by a user with admin rights, it will also update these registry settings when it's closed unless the registry setting is "read only" (!).
  From WizTree 4.27 onwards, the installer will automatically create the necessary registry entries if it's run with command line parameters /supportercode=xxxx-xxxx-xxxx-xxxx, /runasadmin=TRUE/FALSE, or /checkforupdates=TRUE/FALSE
  To set runasadmin / checkforupdates to read only, use:
  /!runasadmin=TRUE/FALSE, or /!checkforupdates=TRUE/FALSE
