Hey there, After downloading iTunes 7 I downloaded the new version of QuickTime as well, so I could see preview videos in the Store browser. Well, when I ran the installer, it told me that there's only about 200MB left on the startup disk. What the hell? I don't have more than 6 GB of music on this entire machine. It's a g4 iMac, 80GB HDD. I've got no games or memory hog applications on here, its just a basic use system. Is there some sort of utility or program I can use on OS X to specifically see what's taking up how much space on my drive, like a pie chart visual or something? Is there just an error with the disk or what? How can I fix this? I'm positive that this thing is nowhere near full whatsoever. Thanks!
