# WinDirStat Application: WinDirStat team Also called win dir stat, windirstat treemap WinDirStat team, System A classic treemap disk-usage tool. The process is windirstat.exe. It is slower than WizTree on NTFS. It is not WizTree. ## What you need to know WinDirStat is the classic folder walk. WizTree is the faster NTFS MFT map. WinDirStat draws a treemap by walking directories. Get it from windirstat.net. On NTFS, WizTree is usually quicker because it reads the MFT. TreeSize is JAM's paid family. - **What is it?**: A classic disk-usage treemap **Same as WizTree?**: No. WizTree reads the NTFS MFT **Why is it slower?**: It walks folders instead of the MFT Feex says If you want the classic treemap and you are not in a hurry, WinDirStat is fine. If the volume is NTFS and you want the map now, I would open WizTree instead. ## What is WinDirStat? WinDirStat walks the directory tree and draws a treemap. windirstat.exe is the window. WizTree64.exe reads the MFT first. TreeSize.exe is JAM Software. ## If you have never used it If you want a colored treemap of disk use, WinDirStat is the classic free scanner. Download it from windirstat.net. It walks folders, so it feels slower than WizTree on NTFS. It is not WizTree, not TreeSize, and not Storage Sense. ## What is it used for? **See a treemap of the drive** Colored blocks are folders and files. WizTree also draws a treemap after a faster NTFS read. **Clean from the list after you look** Delete with care. TreeSize paid adds reports. WinDirStat is the classic free walk. **Scan a folder, not only a whole drive** Pick a path. That walk is why a huge tree takes time. WizTree's MFT shortcut is the other method. ## Who is it for? - People who learned "WinDirStat" as the disk-map name - Users who do not want a JAM license - Anyone comparing speed with WizTree on NTFS ## Current status WinDirStat (2003) is a current disk space analyzer from WinDirStat team. The vendor still points Windows users at https://windirstat.net/. ## How old is it? WinDirStat started in 2003. WizTree (2016) is the faster NTFS MFT reader. TreeSize (1996) is JAM's product. Current WinDirStat still ships from windirstat.net and GitHub. ## Versions Major channels first. Exact build numbers are not all verified here. Windows install GitHub current builds ## System requirements Values follow the publisher's public guidance. Workload still changes the real need. ### Minimum | Operating system | Windows 10 or Windows 11, per current windirstat.net / GitHub Windows builds | | ---------------- | ---------------------------------------------------------------------------- | | RAM | Enough for Windows plus this app. Heavy projects want more. | ## Resource profile - **CPU demand**: Rises while walking the tree **Disk demand**: Lots of metadata reads ## Installed processes These executables belong to this product when it is installed. | windirstat.exe | Treemap window | | -------------- | -------------- | ## Startup components WinDirStat should not start with Windows. ## File locations | Typical install | C:\Program Files\WinDirStat\\ | | --------------- | ----------------------------- | ## File formats It reads the file system. Exports vary by version ## Common problems ### Scan feels stuck on a huge drive It is walking every folder. WizTree's MFT read is the faster NTFS alternative, not a WinDirStat crash. ### Old third-party installer windirstat.net and the GitHub org are official. A "WinDirStat Pro" ad is not the team. ## Getting unstuck ### Download from windirstat.net WizTree is at diskanalyzer.com if you wanted the MFT tool. TreeSize is at jam-software.com. ### Run as administrator if Program Files looks tiny Access denied hides size. That is permissions, not a missing WizTree install. ### Let the walk finish before you quote a number Partial maps lie. WizTree finishes the first NTFS pass sooner. ## Alternatives WizTree for fast NTFS. TreeSize for JAM reports. Storage Sense does not draw this treemap. ## Official help and downloads Start with the vendor.
