I've moved (not copied) my iMovie files to an external hard drive, emptied trash, and rebooted but this has still not made a difference on my hard drive. My movies are showing up as the majority of space. Any thoughts? I have a MacBook Pro and I'm working with iMovie '11, OS X, and Mountain Lion. Is there somewhere else they would be stored? When I moved the files, I did it within iMovie. I'm somewhat new to Macs and thought I knew how to do most of the basic things, yet I can't figure out where these files are!
