Hey, I just tested out WhatSize. It's pretty good! It only freed up about 0.5GB for me though, since I would like to keep all of the other stuff that is taking up a lot of space.
Oh, yeah. So now I have 5.88GB available on my 40GB hard drive (It was as low as 1.67GB until I deleted Quake 3 :'( ). Curse you 3GB of free music from SXSW! 😀 (If I had an iPod, I could free up 6GB worth of songs) 🙁
BTW, I'm making a movie, and that's taking up 11GB right now, and that's why I'm trying to free up space. Oh well, to the guy that was having problems, reginaoak, good luck!
