The game primarily reads these files from the data_win32 folder inside your Far Cry 3 installation directory.

It relies entirely on the corresponding .fat file to be decoded by the game. Common Location in the Directory far cry 3 soundenglishdat and soundenglishfat files

The audio data is encoded using various formats, including:
