From the developer:
FreeDiskSpace is an application that helps you get your disk space back in minutes. The program uses advanced visualization algorithms that hide details and allow you to zoom in on space wasters quickly. The easiest way to free space is to locate large files and folders you no longer need. You can drill down on large folders in the tree map by clicking on large boxes in the tree map view.
You may want to check out more software for Mac, such as Mac Pilot, Dock-It or AppTrap, which might be similar to FreeDiskSpace.
