2. The Dunia Engine and the .DAT/.FAT Architecture

To understand the significance of "72," one must first understand the Dunia Engine 2. A heavily modified branch of the CryEngine, Dunia utilizes a specific archiving philosophy.

Unlike standard file compression which merely saves space, the .dat (data) and .fat (file allocation table) structure acts as a literal database for the game's assets. The .fat file serves as the index, telling the engine where specific textures, XML configuration files, and entity data reside within the corresponding .dat blob.

In the context of Far Cry 3, the patch.dat and patch.fat files are hierarchical. They do not contain the core engine executables; rather, they contain the "patch" data that overrides the base game files located in common.dat. This system allows developers to push updates without forcing players to re-download gigabytes of static data. The "72" identifier likely refers to the internal build number or the file size characteristic of the original release, distinct from later versions that patched in features like Far Cry 3: Classic enhancements or removed licensed music tracks.
