Errr... that much I know, but replacing or modifying a listfile that is already inside a warcraft map's MPQ, then saving that MPQ with the modified listfile with the warcraft 3 map is what I want to know how to do, if you have an answer for me or if you need me to clarify what it is I'm trying to ask please reply, and thanks in advance.
EDIT. Nevermind, I figured it out.
