A question about the Blizzard campaign maps

I'm curious as to where I can extract the individual maps from the blizzard campaigns, I thought I read about someone doing it and it being fairly simple, but I looked around the MPQs and couldn't find it.

What I'm trying to do is open an expansion campaign map, Chapter 3 of the undead campaign to be precise, I'm trying to figure out how to make hostile monsters wander a small area without using the ability which causes them to run when they get hit.

Get WinMPQ, and open up War3Xlocal.mpq It has all the campaign files, you should find what you're looking for pretty easily.

Ah, thanks, that's why I couldn't find the maps. I was looking in the wrong MPQ.
