does anyone know a free software that will graph the directories on my hard drive and sort them in order of largest size?

  • @Bobby So how do you know the user is on Windows?

  • @Daniel Beck: Good point...was a wild guess, a Linux/MacOSX/anyOtherOsUser would have, most likely, mentioned it.

I've had really good luck with windirstat, if you're on Windows of course.


You can use utilities such as KDirStat (Linux/KDE) to visualize where your free space went.

WinDirStat is a similar tool for Windows.

Disk Inventory X is for Mac OS X.

  • Very succinct answer and I like the screenshots. I've used gt5 on linux in the past but I'm going to give kdirstat a try. Feb 18, 2015 at 16:21

For windows- have a look at getfoldersize - it doesn't graph but it does sort by usage and allows you to drill down and find high usage sub directories etc.


If you're using a *nix environment it's quick to just use du -sh /dir to find offensively sized directories. It's somewhat crude, but quick and effective.
