hey guys. ok, i know this is a stupid question, but i have never done this b4... im gonna get an external hard drive, like 500gb, to back up all my music, movies, pictures, and game files. how do i copy game files into my external, and will that enable me to copy them back onto a new comp hard drive later on after i install the games again? how does the backup of game files work, where are they on my comp?? thanks!
