Overall Structure of Game Files

Most of the game files, including 3D meshes, textures, audio samples and game object libraries are located in the cache directory in the game's installation files. All of them are cryptically named with hex characters plus a .pc file extension. The cryptic file names are resulted from applying a 32-bit hash function to their original file paths. For game object libraries and audio samples, their original file paths or file names are stored within the game files themselves and can be extracted.
