WinDirStat is a program that allows you to find disk space hogs at a glance. It achieves that by displaying a drive, drives or directories in a treemap that assigns bigger areas to bigger files and directories. Making those areas visually separate by coloring and other means allows you to see literally at a glance what the space hogs are and where to dig deeper.

The directory tree is simultanously shown as a treelist and as a treemap. One can effortlessly gain an impression of the proportions on the hard disk(s).

Major features

  • 3 views, Directory tree, Treemap and Extension list, coupled with each other,
  • Built-in cleanup actions including Open, Delete, Show Properties,
  • User defined cleanup actions (command line based),
  • Language is English by default; further translations can be added as resource DLLs,
  • Online-Help,
  • A little setup.exe which installs the files and shortcuts.


The original author of WinDirStat was Bernhard Seifert and it was inspired by KDirStat and SequoiaView. Design and many details are based on KDirStat, so WinDirStat is "a KDirStat re-programmed for MS Windows".
