Strongly recommend using something like Advanced File Renamer, or Adobe Bridge for a project like this. What I did was batch rename all my photos to their respective dates/times so each filename is both unique and informative. It also makes it easy to restore your metadata in the future if it ever gets stripped during a file transfer or something; You’ll always know what date/time each photo was taken just by looking at the file name.
