Ok, I have had this probelm with iTunes for some time (from about version 2). I have about 11Gb of music in iTunes. However, if you look at the size of the iTunes music folder (standard location), it is nearer 15Gb!! iTunes is creating hundreds of 3Mb Xml/temp files. This is really getting me annoyed now. I have tried deleting them, but they just re-appear over time. Anybody know how to fix this problem? I cant keep throughing away Gb's of disk space.
