Hello: I recently purchased an 80GB firewire external drive, and have started importing clips to make a soccer video for my daughter. I saved the iMovie file to the external, since it has lots of room and my hard drive doesn't. When I was done, I went to the folder on the external, and the iMovie project file was there, but that's all. No support files. I know iMovie uses reference files to the original imported clips. I went to the "users" folder on my hard drive and looked in the "movies" folder (thinking it must be the default location), but the clips weren't there either. I couldn't find a preference for where I want to save everything, so where might they be? I'm thinking the original clips are now taking space on my internal somewhere, and I want them on the external. Thanks for your help!
