Archer30, thanks for feedback! You are always attentive and positive )
Right, file names from mods have arbitrary naming with/without zero before counter and accounting all of them require mod version 2. Such smart mod can be written, but it equires time.

Btw, total commander allows mass files renaming using counter and mask, so it's fast operation. But I agree, scanning directories and normalizing file names in them would be a killer feature. It's a pity, that I had no such proposal before.
