Unrecognized files on a server.

[AADiC]

Noticed these on a server and not sure what they are, any ideas?

C:\Program Files\Call of Duty\main\vokfixed.pk3 (36 files)
C:\Program Files\Call of Duty\main\ServerPatch.pk3 (8 files)

vokbeta.pk3 is a custom map!!!!

the other maybe is a serverside mod or something dunno....
