"The Club" Unknown Files

Hello Guys & Gals…
.
Don’t know if this has already been posted (@Admin: feel free to del the subject or to move it to another place)
.
i managed to get rip the ‘pak’ archive file from “the club” (this PC game got real nice/cool original models)…but i have a list of files i can hardly open…even if i googed a little 4 it.
>> pcm,pct,pcp,pcc … (see the pic below)
.
i’ve up one of it: fe_kuro_skin.pcm (one of the biggest). Could be its a tex or a full figure package…don’t know.

.
As it seems this game has not been ripped so far…
