Open Source: WinDirStat

More Open Source goodness. WinDirStat

WinDir Stat Main PageOK this one comes with a serious “WARNING. WARNING. Will Robinson…. DANGER DANGER”.

WinDirStat is a disk usage statistics viewer and cleanup tool for Microsoft Windows. It reads the whole directory tree once and then presents it in a bunch of 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

The picture at left gives you an idea of what it will look like. It is a really powerful and useful program. But you can do a lot of damage with it.

Remember ‘WinDirStat doesn’t kill hard drives… people kill hard drives”. I can’t believe I just wrote that. Oh yeah I am SO going to hell

Update: Have a look in the Comments at Marco’s blog. As well as writing his own (Treepie) there are some other programs listed in the same theme.



  1. Thanks Marco,

    You should have also mentioned that yours is Open Source (BSD License).

    I like some of the other ones you mentioned in your blog.
