Disk Inspector is a little program check statistics on your disks and folders. For example, if you need to remove some
files, because your disk is full, you like to see how much files you have, and where they are mostly located.
Also, is it most pictures, movies, MP3s, documents, or?
Disk inspector is currently under beta version. Which means, it is fully usable, but it not fully featured or bugfree yet.
