I found the command a couple of weeks ago somewhere on this forum and for the life of me I cannot find it again... Does anyone know the command to run against a temporary staging storage unit to find out which images have already been duplicated and are candidates for deletion if required by the high water mark.
I couldn't find the thread you're talking about but I believe you just need to run a `find` against files ending with the ".ds" extension to determine your candidates.
A search on this forum using "DS" brings up a few messages from Bob Stump talking about how to manually bpexpdate what you find. I hope this puts you in the right direction!
