The ba2 file extension is nowadays mostly related to special game archives used by the Fallout 4 computer game from Bethesda.

These archives may contain anything, including textures, meshes, voices, maps and more.

Two types of ba2 archives exist: generic and texture. Generic archives can contain anything, while texture archives are optimized for storing textures.

There is no significant size advantage when comparing the two, but texture archives store textures in a more intelligent way that is friendlier to the runtime texture streamer.
