In this case, pay attention that the renumber script does
not pay attention to not overwrite files. This can lead to
problems when adding files. Let's say you have


and add a file new.jpg, so you have


If you now run

	renumber pic jpg

you'll have

	pic_01.jpg = new.jpg
	pic_02.jpg = pic_01.jpg
	pic_03.jpg = pic_02.jpg
	pic_04.jpg = pic_03.jpg

and the "source pics" will be "removed", so you end up with

	pic_04.jpg = neu.jpg

A workaround is to use the MC to prefix all files with an
arbitrary letter, and THEN run renumber, e. g. select all
(grey *), PF6, to "X*" (where "X" is the arbitrary letter)
and have


which can be processed with "renumber pic jpg" now without
any problems because the existing prefix isn't the same as
the renumbering prefix.

As you see: I have a reason to believe that I should better
write a new script that takes such things into mind and maybe
offer reverse renumbering, overwrite protection and a better
selection which files (instead of hardcoded *) to process.

It's worth it. The MC is a powerful and still easy to use
tool for file administration.
