Wondering where all your hard drive space went? WinDirStat is a free open source program that shows you your disk usage statistics and helps you clean up unneeded files.

The bottom half of the screen is called a treemap, a concept invented by Ben Shneiderman, who happened to be my human-computer interaction professor at Maryland.

In the above treemap you can see that large blue rectangle taking up a lot of space. According to the key on the top right, that is my VirtualPC virtual machine image, which I used to play with an early build of Longhorn. I would have forgotten about that huge file if it weren't for this program.
