XBOX 360 Models and texture conversion

[Smakkohooves]

I actually try to rip models from a xbox 360 game, but im stuck with a bunch of unown files....
These are the file format:
 
.XFD .XFT .XNM .XTD

I'm stuck here just looking at this files, 
no one knows what they are.

*Update*

I found something here, but im too noob to understand what i have to do....
