Hi, I am in need of saving some space on my Mac. I have noticed (especially with pictures) that there are a lot of duplicate everything in my hard drive. The trouble that I'm having is sometimes when I try to delete pictures it says something about an original alis not being found; so I cant delete it. Any help/tips on how to delete things would help, for I'm no computer wiz. (I have a Mac OS X, with latest software 10.6.7) Thanks!
