How do I extract files from the War3.mpq and War3x.mpq

I need to extract the .ai files from Frozen Throne... I used to remeber how to do it, but I can no longer remember... It's been awhile since I've done any War3 editing.

To extract the mpq's, u need an mpq extracter (well, obviously :D ). i use winmpq, but theres numerous ones around, i think there at least 3 in the downloads section. then just open the mpq u want from your drive and it will open it. if your using winmpq, jsut right click the file/files u want to extract, and an option 'extract' will be there with a few others. just select the folder u want to extract them too, and hey presto, .ai files to go! hope thats clear enough. if u dont have an mpq extractor, get it from the downloads section, and ive found winmpq is the easiest, but thats just my opinion. good luck :D
