FWIW, I'd probably handle a renumbering exercise like that by making a script to do it.

I can only half help on how as I do these things in Linux, not windows, but I would list all of the filenames into a file, one per line, duplicate all the lines as "existing file name" <tab> "existing file name", then change all the instances of <tab>[1-9] to <tab>0[1-9], hack the last few manually and change the start of each line to mv<tab> which IIRC would be ren<tab> in windows, then test and run the script.

The gotcha in this is always filenames that contain special characters that the script or shell interprets, e.g., ' " and the like. Caveat emptor.

A simpler way still might be to list only 1-something files first and rename them, then do 10...99-something files as a second exercise.

IIRC there is some clever(ish?) rename trick in Windows, but I'm afraid I don't know it. Someone else may have the method.
