In a matter of less than a year, I filled my harddrive of almost 100 Gb of stuff. I cleaned up most of the stuff, but freed hard drive space but with very little success. I have summed some of the items I have on my Powerbook, but is still too full. I thought of cleaning up completely my hard drive and start over. The truth is that I have so much stuff, my keychains, configurations to websites, imovie projects, iTunes lib, iPhoto lib (all massive), but still there is about 40 Gb of info I can't seem to find. I know that Apple hides a lot of files from a regular user, but my hard drive space seems not to get any better. Now, Instead of formatting my drive and migrate my files outside to bring them back in, I tought of transfering my files to a new user account and wipe out the old one, all within the same powerbook. Keeping in mind that I am looking to Clean "Neat" hard drive and still leave my powerbook's information intact, I have the following questions: 1. Is this procedure going to help me really to recover my lost space? 2. How exactly do I migrate my files from one account to the other? 3. I have an Intel Mac at home. I could use the migration assistant to migrate my powerbook's info to a temporary account in my intel mac and then format my powerbook and then retreive the info back, should I rather do that? Thanks!!! My model is: 1.62 G4 Processor 17" Inch screen.
