Assuming you keep iTunes on the default setting and let the app manage your music files and songs, iTunes will store all of your media nicely in the Music directory of your home folder, with each song kept in a folder according to the album and album artist. Though you’ll usually never need to directly access those files directly, if you’re looking to move your iTunes library to another location or external hard drive, back up your music manually, or make edits to songs directly, you will need file system access to the iTunes music files on your computer. We’ll point you to a super fast way to reveal and access any single song in OS X or Windows, and also show you where all the music files (and entire iTunes library) is stored in both Mac OS X and Windows too.
