WinDirStat: Windows Directory Statistics is a Windows utility which allows you to view disk space usage, broken down by:

  • Folder/Directory – percentage of parent folder allows you to identify the folders taking up the most space.
  • File type summary – useful for seeing how much space your pictures take up
  • Individual files

The graphical view, called TreeMap, allows you to easily identify the largest files.

WinDirStat

After installing and letting it analyze my disk, I was able to instantly free up 2.0 GB which was used by archives of old database backups I had forgotton about.

WinDirStat took 12 minutes and 39 seconds to analyze my disk which contains 36, 406 folders and 460,374 files totalling 54.5 GB.

And the best bit it is open source (hosted on SourceForge.net) and free.

    My program is open source and free as well. And it’s maybe 10 times lesser then WinDirStat in its own size – http://soft.km.ua/soft/dirlot/index.en.html

    Have been using WinDirStat for several years to free up space on file servers it is particularly useful for explaining to users why having 10GB of videos, music and games is a bad thing.

    Regarding the previous comment, I have never used DirLot I am however very interested and will try it out on Monday to see how it works.
