FastFiles are the CoD engine's way of storing Zone files. FastFiles (FFs) almost always have some sort of RSA2048 signature, a zlib compression along the way, and then on later CoDs some encryption. The Zones are a library of assets. Every FF in every CoD game starts the same way...

struct DB_AuthHeader
  char magic[8];
  int version;

So by reading the version of the input FF, you can tell what system and game the FF is from.
