Typically, PC users will find their original i Tunes library content in this directory: C:\Documents and Settings\"USERNAME"\My Documents\My Music\i Tunes\i Tunes Music The default i Tunes library folder for Mac users is: /Users/"USERNAME"/Music/i Tunes/i Tunes Music Of course, we advise that you be cautious whenever you delete something from your computer.
It's never a bad idea to back up your i Tunes library using either Time Machine on a Mac or the "Back Up To Disc" feature in the i Tunes File menu (located within the Library submenu) on a PC.
Even though your old files are long gone, i Tunes will not delete its record of the file simply because it can't be found.
