MMario -

It's a good idea to look, with the attrib and/or dir command, to check the "spelling" on short file names. They get assigned based on the "order of installation" so they may differ between machines - even for fairly standard stuff; and sometimes they actually may change on-the-fly, especially for a few system files that really do get moved around or "rebuilt at boot" on the machine.

The newest versions will generally let you use the long file names shown in Win Explorer, but there's been some variation between versions, so you have to try it to see what works.

Actually, in newer Win versions, you can use the DIR command with the /A (Attribute) switch to list files with a particular attribute, so you don't really have to resort to ATTRIB to find the "hidden" and "system" folders. I'm just generally too lazy to look up the switches, and ATTRIB is simple to use - and works.
