Hey guys; So, I have a MacBook Pro with a 320 GB HDD, and I'm down to ~90 GB left. This surprised me a little bit, as I do feel that I have 200 GB worth of information stored on my HDD. I'm wondering, is there a program/way to be able to see exactly what is stored on my HDD, and how much space it is taking up? My biggest worries are things like: Song/Movie duplicates, install/update files on programs that I have installed and then removed, and programs that I don't realize/remember are as big as they actually are. Basically, a way to really clean up my HDD? Thanks for any/all help!
