I still remember thinking the 10 GB drive in my Apple computer PowerBook G4/400 was more than I'd ever need - but only until I migrated to OS X. Then it was time to move to 20 GB, and someday soon I'll be replacing that drive with a 40 GB one. Part of that is because OS X is huge in comparison with OS 9. But a big part is programs and installers that accumulate and never get removed. So I decided to look at the 80 GB hard drive in my iMac to see how much unneeded stuff I could eliminate. And a ton of useless files have been found. A good free cleaner for Apple computer is really necessary to save your previous disk space.
