OK I made 2 accounts and then decided to delete the new account I created. When I created the new account, I had about 17.3GB free. Then around 6PM I noticed that I had 1.8GB left!!! Where did it go? I'm not missing any folders because I can find all of them. PS - The iTunes library got messed up and now all my music is gone (1300 songs). Although they remain in their folders in the iTunes library. I decided to move about 850 songs back into the iTunes (drag-and-drop). It took about 15 minutes to finish COPYING them. Was that what did it? My iTunes library was 14GB in size before today. What do I do? Can I see a graphic of what file or folder is taking up the most space?
