Long file names are NOT a good idea. Your experience is a prime example why.
We stick to a very simple “date/camera/load” system for filenames: Example: 725A03 (July 25, A camera, third load). All of the “cu of girl ” etc. goes in the “comments” column.
FCP 6 now has a “file renaming” function that will match the browser filename to the finder file. This may help you, but be CAREFUL doing that. You mentioned you’re on X-SAN. If you rename a clip at the finder level, anyone else who’s already used it will now get knocked off-line and have no idea what your new name is.
Bottom line: Short file names.
