Not a storefront, but a huge (and slow) program. With over 9000 pictures in there somewhere, it's time to 'tidy up!' But it's not that simple, apparently (thank god I read up on the process!) WHY it's not real simple is beyond me - I'd expect this to be a common desire.
Apparently you can lose files when you do it the wrong way. The right way has been described simply (with a warning to try on a small number of the files first - just to be SURE...) and also in a long 11 step process. I don't understand all of the steps, either!
So I sit and wait for the "Reconnect missing files" command to do about 100 searches - this could take all day. Then I have to carefully (like an egg on a spoon) move them to the outboard drive.
From what I read, if you don't do this properly, you'll 'blind' the program to the pictures. Or, you lose them.
