Where did my disk space go?

Sometimes I wonder where all my disk space went. It's not that I have much of it, it is simply that I don't have a clue where did it go. And the more I free up, the more it keeps on disappearing.

Well, Filelight is the answer. It scans any directory, even remove ones, and displayes the usage in a comprehensive, zoomable, pie chart.

Suddenly, there they were... the forgotten files that were eating up my disk space... squash... squash... killed!
