Hi all, I'm running low on disk space on my macbook. I'd like to move ONLY my movies/tv shows to an external drive. I have a couple of questions: 1) How does one do this? Can I drag only the movie folder onto the external drive and leave the music folder on my macbook? 2) If I get new movies, do I have to individually put each onto the external drive? 3) If I'd like to those watch movies on my apple tv, do I need to attach the external drive to my macbook? To the apple tv? Can I attach it to my airport extreme base station, so it's shared over wifi? I appreciate the help!
