when i try to back up an iMovie project to my external drive (by copying it over), i get this: "You cannot copy the Item "Icon" because the name is too long or includes characters that the disk cannot display". yet the file does PARTIALLY copy to the external drive (at least its icon appears), but when i try to open it by double clicking it just launches iMovie but doesn't load the actual project. i COULD create a full quality QT file of the project and copy that, which would be a bit of a safety, but obviously it wouldn't be including any of my actual edits/timelines/clips, etc...all the stuff that is vital to protect! there has to be a way of backing up the entire project to another drive- but iMovie's Help doesn't have anything, nor does any iMovie book i scan through in the bookstores. ????
