As part of an attempt to move a Photoshop Elements catalogue, I moved thousands of photos out of Dropbox for safekeeping, offline so they'd stay intact on other computers and in the cloud. Then after installing the program I did the work to prepare for the photos to be indexed. Then I moved the photos back into Dropbox but forgot to take the computer offline, so all 27.5K+ files have now synced to the Cloud. But because they had the same names I now have the originals and copies. Is there a way I can identify all the Dropbox files that were uploaded today, or any particular date, so I can delete only the copies?
