Hello. First of all thanks for this application. I have used it for some basic yet would be time consuming tasks.
I have a question which may at first seem like the what the last person asked, but with an important twist.
I wish to subtract (5389) from the last four digits of my file name. That is to say "DSC07820" would become "DSC02431".
But it has to be subtracting because I wish to keep any "gap" in the series after the rename. For instance:
DSC07820 -> DSC02431
DSC07821 -> DSC02432
DSC07823 -> DSC02434
DSC07825 -> DSC02436
DSC07830 -> DSC02441
So I can not simply remove the last four digits, add 2431 and increment from there.
Cheers.
