I prefer a symlink because it saves me having to re-hook the library, and I've had Link shell extension in my toolbag since it was beta'd on NT4, I often forget it's not part of Windows

Can you post the templates used for the Formats and Annot? columns
IIRC there are two format functions one that lists what the database 'thinks' exists (its name is something like approx_formats), and another that lists what the file system actually has. Can't comment on Annot?
