WizTree is a 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.
Which file system does WizTree support?
WizTree scans all hard drive types supported by Windows (NTFS, FAT, FAT32, network, etc). Storage devices in phones and cameras can also be scanned when connected via USB.
Is WizTree free?
Yes, WizTree is free for personal use. If you want to use it commercially, you can purchase a “supporter code” or an enterprise license.
Is WizTree compatible with macOS?
WizTree is Windows only, but an alternative for macOS called GrandPerspective works similarly.
Are there other good alternatives to WizTree?
Other recommended disk space analyzers for Windows include Space Sniffer, DiskSavvy, WinDirStat and TreeSize. All of them are free.
Why do I need WizTree?
WizTree scans your storage drives in real time and lets you visualize how your files and folders are structured and which files are taking the most space. WizTree is great for identifying big apps or files you can delete to recover space on your storage drive.
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.
Features
Disk Space Analysis
Quickly identify what’s using up the space on your hard drive and optionally delete files and folders to free up space.
Extremely Fast!
WizTree reads the Master File Table (MFT) directly from NTFS formatted drives (similar to the way Everything Search Engine works)
Multiple File Systems
WizTree can scan all hard drive types supported by Windows (NTFS, FAT, FAT32, network, etc). MTP/PTP devices like smartphones and cameras can also be scanned when connected via USB.
Visual Treemap
The visual treemap displays all files and folders visually based on their size. This allows you to spot large files and large collections of smaller files at a glance.
Find Largest Files
The “File View” lists every individual file and folder on your hard drive in order of size.
File Name Search
Quickly locate files by name or type using the file view search filter. Wildcard searches also supported (e.g. *.mp3)
Export File and MFT Data
All or selected file information can be exported to CSV (comma separated values) file or copied to the clipboard. MFT files can be extracted and dumped to a file.
Import File and MFT Data
Exported CSV and dumped MFT files can be imported back into WizTree for viewing. Great for tracking file system changes over time.
Command Line Support
Exports of CSV and MFT files can be done via command line parameters. Great for automated auditing of hard drives.
It’s free
WizTree is free for personal use. However you can help support further development and use it commercially by purchasing a “Supporter Code”. Large organizations should purchase an Enterprise license for unlimited use.
What’s New
- UI tweaked to look like Windows 11 style
- WizTree can now export/import “.tsv” (tab separated values) files. Simply set the file name extension to “.tsv” when saving to enable this, otherwise it will use a comma to separate the values
- Some UI elements would be slightly blurry on high DPI screens – fixed
- Deleted files will now be marked with a red outline in the treemap as they are detected
- Fixed treemap hover glitch which could happen in certain situations when deleting files
- Various translations updated
- Fixed rare bug that might cause some folders not to be detected by WizTree when parsing MFT file due to unusual MFT record ordering
- Tree, file and extension views text size can be increased/decreased by using Ctrl+MouseWheel
- When importing CSV files WizTree will now display the line number containing invalid data that caused the import to fail. Useful for those who create WizTree compatible CSV files
- Added new “Reset Configuration to default values” function to the File menu. This will set all but the licencing info back to default values. Use this if you notice anything weird happening (like very large or small column widths, font sizes, etc)
- WizTree will now by default display the maximum “last modified date” for all files and folders within a folder instead of the standard Windows last modified date. This will only apply to new installations or when resetting the configuration. To disable this edit the WizTree3.ini file and change the following setting:
- ShowMaxModifiedDate=0
- WizTree will now default to sorting by “Allocated” space instead of “Size” as this better reflects actual space used by files. Allocated space will now also be displayed on the Treemap by default. This will only apply to new installations or when resetting the configuration
- Installer has been updated to use the correct configuration file location when being installed to a non “Program Files” location. If WizTree detects it’s running from the “Program Files” folder it assumes it’s the “installed” version and keeps the config file in the %appdata%\WizTree3 folder, otherwise it will keep the config file in the same folder it’s running from. Previously the installer would always assume the config file was in %appdata% folder, which would be incorrect when installing to a non default location.
- This is useful for Enterprise users running automated installs as the “SYSTEM” user as the various config command line parameters will now be applied to the correct configuration file.
- e.g. to do a silent install of WizTree into the “C:\WizTreeApp” folder with no desktop icon, auto configuring it to not run as admin, disable checking for updates, and setting the license key:
- wiztree_4_14_setup.exe /DIR=”C:\WizTreeApp” /VERYSILENT /SUPPRESSMSGBOXES /NORESTART /SP- /MERGETASKS=!desktopicon /runasadmin=false /checkforupdates=false /supportercode=xxxx-xxxx-xxxx
- Installer will now update the registry to make mapped network drives that were created by non elevated processes visible to elevated processes like WizTree. This will require a restart to take effect if not already enabled.
