OK, here it goes, im running windows vista on my pc and recently installed the new iTunes so i can use my pc to put music on my iphone, previously, i was using my laptop which is running xp to put music on my phone, and by doin that i needed to burn the music onto a dvd then transfer to my laptop then onto my iphone, which was a bit of a bother, so i installed swaptunes on my iphone so i could use my laptop and my pc to add music, but when i installed swaptune all it did was converted ALL of my music (4.3gb) into "Other Files", what is the easyiest way to delete these "other files" or convert them back?
