I hate asking questions that make me sound like a noob, I'm certain there is a way to do it just haven't taken the time to figure it out. I have all of my movies and TV shows on my external HDD, how do I direct iTunes to those files in bulk without having to select each one and tell iTunes where the file is? Is it holding the option button when opening iTunes and creating a new library? If so then when I add new files to it will they automatically go to the external, assuming its plugged in?
