in the library of itunes at the bottom of the application, it says there are 17.13 GB worth of files, but my itunes folder says that it is only around 15.54 GB worth of files. are there music files that don't go to the itunes folder. or do non authorized files not go intop the itunes folder i am saying this because i am transferring all of my music through External hard drive to another computer and i don't want to lose anything.
