iTunes size - 45.2GB, iPodContent - 46.1GB?

My Dell™ Inspiron™ 1545 hard disk was low on space, about 5% free. I find that two folders both contain about the same amount of space used for music, Music/iTunes at 45.2GB and Users/Rob/Documents/iPodContent at 46.1GB. Both contain the same tunes. Of course, I also have them in my iPod Classic.



Is this normal or can I safely delete one of them?



I have also found that I have lots of duplicate files. For example Imagine, Imagine(1), Imagine(2) and all the way to Imagine(6). I have been deleting them and all seems to be OK but, how am I getting the duplicates?



Thanks, Rob
