I may not be able to do anything with these myself, but so I can at least feel somewhat useful, here for all intents and purposes on decrpyting the config files ect are all of the files included in the 'players' folder. From the looks of it, there are seperate files for zombies, multiplayer, and campaign, aswell as button binds and actual optional settings(this is purely based on assumptions from the original files names). Good luck.
btw, this is like my first post and I honestly dont know how to post virus scans, so if that is necessary then I would appreciate some help on that
