Where are the official maps?

Hello,
When i had only Reign of Chaos, the official Blizzard maps were in the war3.mpq file and easy to extract. Now i have The Frozen Throne, but i can't find the maps of the new campaign in any of the MPQ files, does anybody know where they are? I want to study from the triggers they used. Thanks in advance.
greetings,

I'm pretty sure that the Orc campaign files are in war3patch.mpq, and most of the rest of them are in war3local.mpq.

Thanks, i've found them
