BSA Files

BSA (Bethesda Softworks Archive)

BSA files are archives that contain all the game data. Mod creators who wish to create custom meshes and/or textures, or alter existing ones, will first need to unpack the game's BSA files. Programs with the ability to unpack BSA files are listed here: BSA Unpackers
