WinDirStat is a disk usageÂ statistics viewer and cleanup tool for MicrosoftÂ Windows.
On start up, it reads the wholeÂ directory tree once and then presents it in three useful views:
- TheÂ directory list, which resembles the tree view of theÂ Windows Explorer but is sorted by file/subtree size,
- The treemap, which shows the whole contents of theÂ directory tree straight away,
- The extension list, which serves as a legend and showsÂ statistics about the file types.
