THanks for that, so I am I correct in the following ,IM trying to make a expansion called Nap.

So I if want to use the orginal MTW stategy maps so should I copy the following files

minilukup
MINIMAP
MINIPAN

and rename them as

Nap_minilukup
Nap_MINIMAP
Nap_MINIPAN

Ive made new campagains before but never used the SetMapTexturesSubdir command before (ive used the vikings sub folders for UK based campagains)

But this time I want to use battle maps from the Lordz napoleonic mod so I think I need to make this a proper expansion so have to set the stategic map up

Thanks for the help
