As hixxy said you cant make files with these names on windows.
Go on try calling a folder 'con' it will not work.
My point was that some you can, and some you can't - mIRC creates an error message when trying to create folders named IP, GLOBAL, SHADOW, etc - but it does create them. It won't read from IP.TXT GLOBAL.TXT SHADOW.TXT, but Win Explorer CAN create them. However, there's enough of a minefield out there that mIRC plays it safe and stays away from all reserved names.
