Why use WizTree?
Free up your disk space
WizTree makes it very easy to locate and remove "Space hogs" from your hard drive. The visual tree map displays the sizes of all of your files visually, helping you to quickly locate large files and folders.
Save Time
Don't waste time waiting for the disk scan results. WizTree does in seconds what similar applications take minutes to do.
Regular updates
WizTree is in active development and new features are added regularly. If you have any suggestions for new features please contact us.
It's FAST
When scanning NTFS formatted drives, WizTree reads the hard drive's Master File Table (MFT) directly from the disk (like Everything Search does). It can also quickly scan non NTFS and network drives.
It's ACCURATE
Unlike similar applications, WizTree correctly handles hard linked files (doesn't count them more than once). The total allocated space reported by WizTree will actually match what Windows reports.
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 organisations should purchase an Enterprise license for unlimited use.
WizTree
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 & Duplicate Files
The "File View" lists every individual file and folder on your hard drive in order of size. WizTree automatically locates duplicate files based on name, size and optionally date. If a file has duplicates, they can be viewed by clicking on the "+" next to the file name.
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.
