When I look at my iTunes folder in the Finder, it says it's 5.39Gb, but when I browse my entire library in iTunes, it says it's 3.99Gb. I only have an 18Gb hard drive in my iBook, and I need every Gb I can get (photos, multiple users, etc). Why is my library so big in the finder? Is it because of the directory structure (all the folders)? Does this really take up an extra 1.4Gb?!? I was thinking that maybe the size reported by iTunes is just the music data (not counting album art, ID3, etc), whereas the finder is actually all the data. Possible?
