With DaisyDisk you can free up disk space by quickly finding and deleting big, useless files. The program scans any mounted disk and displays it on the sunburst map, where segments mean files and folders, proportionally to their sizes. The map is easy to read and navigate. You can also quickly preview any file and reveal it in Finder to delete. More info »
Awesome interface, nice and clear to know how you're using your HD space.Too bad it costs $19.95(Shareware)
I just downloaded this application yesterday and like how easy it is to use. It helped me find files that I didn't know was hogging my system. Not to mention that it has a nice interface.
