I just downloaded the NW 3DS Studio or what ever the third option is and I have an installation of Autodesk 3DS Max i think it's 7.0 or 8.0. I'll go home and test this weekend and see what happens. Also I'm not sure if this is part of the original question but if I extract a module from KOTOR Tool what is the purpose of those files if you can't edit them in some way, shape, or form?
Oh, you can manipulate them alright! But you must know where to look for and have NO visual support. In the tutorial section you can find all kinds of tutorials. Those can be a bit overwhelming at first glance. You must know that the game is a very complex thing.
As a newbie/noob in regards to modding myself I put together what I learned in this thread which I wrote during lunch breaks, and which is not finished yet. Maybe it is of some help:
