Hey everybody, I'm a new poster, but a longtime reader of these forums. I own a 12" Powerbook G4 that I bought used in January 2005. I've been looking at ways to make space on my hard drive and have discovered a folder called "previous systems" that has a folder for "previous system 1" loaded with nearly 5 GB of stuff that I'm pretty sure I don't need. Is it safe to just trash this whole thing or am I getting ahead of myself?
