Fol001_001.tif, Fol001a_002, Fol002_003.tif, Fol002a_005.tif -and more.
I just want to change the last three digits to be like 001, 002, 003 tif without changing the "FoL" part of the name of the file!
I tried the multiple rename tool, but there must be something else, this did not work

Thank you very much for your help!
