Batch script to partially rename many files

Hi there, I created the following batch file for Windows 7 based on another member's old solution (i.e. related thread is now closed): @echo off cls setlocal enabledelayedexpansion for /f "tokens=1* delims= " %%1 in ('dir /b *.epub') do ( set oldfilename=%%1 %%2 set newfilename=%%2 echo Oldfilename=!oldfilename! echo Newfilename=!newfilename! pause>nul echo.&echo. ren !oldfilename! !newfilename! ) When listing the proposed changes, the echoed newfilename is exactly what I want but the OS comes up with "The syntax of the command is incorrect" when it reaches the REN line. What am I doing wrong???? Thanks!
