WinDirStat (Windows Directory Statistics) is a disk usage statistics viewer and cleanup tool for Windows. On start up, WinDirStat reads the whole directory tree once and then presents it in three useful views:

- The directory list, which resembles the tree view of the Windows Explorer but is sorted by file/subtree size,
- The treemap, which shows the whole contents of the directory tree straight away,
- The extension list, which serves as a legend and shows statistics about the file types.

Visit the WinDirStat blog for more up-to-date information about the program.

Note: If you are looking for an alternative to WinDirStat for Linux, then you are looking for KDirStat (apt-get install kdirstat on Debian-derivatives), and the alternative to WinDirStat for MacOS X is Disk Inventory X or GrandPerspective.

  • Very informative display of storage sections on the computer. It detects an external hard drive but it doesn't seem to find my USB flash drive. Am I missing a setting somewhere because this would be relly helpful.
  • A big thank you to Oliver Schneider, Bernhard Seifert! WinDirStat has been an invaluable tool for me in cleaning up storage space for many years. Hope you enjoy my donation, and I wish others also support you for the times it helped them! :)

  • Perfect for what I needed to do. Gives good details on what's using up space and even has a little pane on the side where it sorts the file types in order of size.

  • Absolutely amazing. I was mad and confused, looking all through the storage settings and disk cleanup stuff to get rid of space on my c drive. I was only able to get around 10 gigs at most. When I downloaded this, it visualized everything and did not hide a thing from me and made it so much easier to cleanup storage. It is the omnidisksweeper for windows. I would 10/10 recommend due to how easy it is to use and just overall amazing.

  • I've been using this program for years and love it. I would love to be able to measure Google Drives which are mounted as a drive, but are not selectable, and see a dark mode option soon.
