I want to clean up my blackbook. I had the 250GB HD and now I'm down to about 83GB left. My music is about 30GB. My applications is about 6.22GB. My partitioned hard drive was 25GB. So where is all my hard drive space going to? I have LOGIC PRO installed (with all the loops), FINAL CUT EXPRESS, APERTURE 2, Ilife 08 apps, etc. Does anyone have any idea so I can find out where a lot of my space is going to? FYI the only copies of my music are in the iTunes folder itself. And for optimizing performance, that's Disk Utility only right?
