I hate to ask this. It seems so lame. And yet after 2 months using Xpress Pro, and becoming a fairly proficient editor, I still don't understand media management very well. In particular, I don't even know which folder should really be "copied" to a disk or external drive to back-up all my editing work (not the master clip files, just the edited sequences, etc.). I see the project bins are all listed in the Avid Attic folder. Is this the one I should be copying to a disk for safekeeping? I can't seem to see the project folders in any other folder, including the one called "Avid Projects" withint the Avid program file program. You'd think they'd be in there! But that folder is actually empty. Maybe that's because they're all being saved to my external drive. I see an Avid folder there with a bunch of .avb files in them for each project. Is that the folder I should be backing up--the ones with .avb files in it? See how lame I am?
