   If you're trying to save as many bytes as possible, try this:   
      
   @setlocal enabledelayedexpansion   
   @if exist %1 for %%F in ("%~1") do @(   
   @set d=%%~tF   
   @ren "%%F" !d:~0,2!-!d:~3,2!-!d:~6,4!%%~xF)   
      
   You save multiple characters by not using @ECHO OFF and instead putting   
   the @ character in front of commands that would otherwise show up on the   
   screen.  -  There's simply fewer commands than the bytes in the "@ECHO   
   OFF" string.   
      
   I also question the lack of (double) quotes around %1 in the if   
   statement.  I guess it's fairly safe to not have them in the new name of   
   the ren(ame) command.  Unless the extension has a space in it.  }:-)
