Can't think of how to phrase this so I'll explain:
I have 100 files. I would like to divide them in batches of, say, 10 (10 batches of 10 files). I'd like to append each part of the filename with a number to indicate what batch it is.
So something like...
(SET1)filename1.jpg
(SET1)filename2.jpg
(SET1)filename3.jpg
...
(SET1)filename9.jpg
(SET1)filename10.jpg
(SET2)filename11.jpg
(SET2)filename12.jpg
(SET2)filename13.jpg
...And so on
I thought maybe using Numbering (10) somehow but no luck. I'm just trying to avoid selecting about 10 files, renaming, rinse, repeat over and over as I have more than 4000 files between 40 or so folders
