What is WizTree?
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.
Features:
- 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 relies on the Master File Table (MFT) during an NTFS drive scan, bypassing the OS and making the scan finish quickly
- Scans all drive types supported by Windows, in addition to network drives and MTP/PTP devices
- Sort the scan results with the tabs, including filetype results
- A treemap that visualizes the files & folders based on their size - can be zoomed in/out and exported to an image
- Find largest & duplicate files with the "File View" and locate by name or filetype with the search filter
- Export file information to a CSV file or an MFT dump, and import it back for viewing
- Command-line support for exporting CSV/MFT files and treemap images
How does it work? 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.










Comments and Reviews
Scanning was extremely fast even on a network share -- about 100 times faster than Windirstat.
After having used Windirstat for "decades" as the best disk usage visualization tool by far, I must say that WizTree is probably the #1 tool to beat now.
On Windirstat, only the Treemap looks a tiny bit more polished on HiDPI screens, because you can make Windirstat show the colored 'file pillows' with a black grid.

Also, when comparing the two Treemaps, in WizTree there seems to be something cut off at the bottom.
Other than that, WizTree seems to be perfect.
This isn't an alternative to windirstat - it's not open source. Having the full knowledge and control over the software is a pretty relevant feature when it's got admin rights to your PC.
Funny how quickly people will sell out their freedom. Yeh, the old one is slower, for now. I'll just start it and keep multitasking like always.
best soft, never crashed, lightweight and increadibly fast, never saw that.
2 bad reviews but not relevants....
Extremely fast and lightweight.
Very fast - uses existing FS metadata rather than scanning each file.
Unless software can do file deduplication (hard links or symbolic links), it does not compare to the functionality of TreeSize.
It has a donate button that's animated every 9th second!
