What are BF files and how to open them

What is a BF file?

A .BF file is a Cryo Interactive Game Data file.

Cryo Interactive Game Data files are archive files created by Cryo Interactive Entertainment and used in adventure games developed by that company (later acquired by Microids). They store many different kinds of game data - such as 3D models, textures, sound effects, music, dialogue, maps - bundled into a single file. These archives serve to package all assets needed by a game's engine into one container for loading.

These archives are not intended for manual editing or typical use by end users. They are read by the game at runtime to retrieve assets, locate sounds, visuals or scripts. Third-party tools such as Unpakke or the Python tool "cryobf" exist to extract their contents, enabling modders or preservationists to view or export internal files.

Cryo Game Data archives start with a signature, a small header that includes metadata and a file table indicating the internal files' offsets and sizes. In the Python "cryobf" tool the archive is parsed by reading entries like file relative paths, offsets, and sizes - e.g. an entry might point to "OGG/BDi_01.ogg" with its size and offset.
