Yep, ta. Saw that earlier.

My code still works for a bunch of folders that are within a single folder.
I thought it would. :)

Since both "REN" and "MOVE" do not support wild card substitution, here is my work-around based on dbenham idea:

Code: Select all

@echo off
setlocal enableDelayedExpansion
set m=0
for %%A in (
  JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC
) do for /d %%F in (????-%%A) do (
  set /a m+=1
  set "mm=0!m!"
[b]  set "year=%%F"
  set "yyyy=!year:~0,4!"
  echo ren %%F "!yyyy!-!mm:~-2!"[/b]
)

Pure batch: Doh :roll: Does not work because wildcard not allowed in REN targe name when renaming folders

Code: Select all

@echo off
setlocal enableDelayedExpansion
set m=0
for %%A in (
  JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC
) do for /d %%F in (????-%%A) do (
  set /a m+=1
  set "mm=0!m!"
  ren "%%F" "*-!mm:-2!"
)

I think a work-around for your above method is like this:

Code: Select all

@echo off
setlocal enableDelayedExpansion
set m=0
for %%A in (
  JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC
) do for /d %%F in (????-%%A) do (
  set /a m+=1
  set "mm=0!m!"
  set "folder=%%F"
  set yyyy=!folder:~0,4!
  ren "%%F" "!yyyy!-!mm:~-2!"
)
