Estract from Pat & Dxd

I have a problem with a dxd pack,
From a steam game, i want estract all the files inside but the only estractor i find estract only some files...

And another problema with .pat files,
From a android game, i know that is a model but dont' know how open it.
Also, in the same game i can see that all the
Files is a .pat files, as the models, the music,
And the other.

Someone can help me with these files?

I post also a .pat that i presume is a model.
