Then .. With the folder sorted by Date/Time Taken ...
I'd select a group of pictures .. and
COPY them to individual folders ..
Like .. Rehearsal, Wedding or Reception.
Then you can do some batch renaming ... Photo repairs .. etc ...
(I would suggest .. Always keep a copy of the originals)
I have a friend who started Photographing weddings.
It didn't take him long to quit doing this ... He got tired of dealing with the Mothers

Good luck
