Fishface told you how in your last topic. (Don't make duplicate topics!)

You need to learn how to batch extract. There are tutorials in the tutorial section.
It's a slightly advanced topic so I suggest you don't jump to that right away because it doesn't seem like you know what you are doing yet.
Just my suggestion. If someone else wants to write up a user-friendly tutorial, go ahead.
