This was my original script, if a file had special characters in it's name like "!" or "?" it would just ignore it and not let me know about it:

@echo off
setlocal enabledelayedexpansion

Can you look through the changes I made, remember then and then when can I send you a new script which also needs the same treatment as I gave that script, but that as to start with script looks much more different?
