“ BSA (Bethesda Softworks Archive) are archives that contain resource files (meshes, textures, sounds, etc.). The GECK does not allow creation or editing of BSA files, but other tools do. ” — Bethesda GECK glossary[1] A BSA file (or Bethesda Softworks Archive ) is a type of archive data file used to store game assets in Gamebryo and Creation Engine games (with the BA2 format replacing it in Fallout 4 Fallout 76 record files . BSA and BA2 files are found in the Data subfolder of any parent game directory (i.e. where the game's .exe file is found).
Individual files can be extracted from BSA and BA2 archives using third party tools such as Bethesda Archive Extractor (B.A.E.).[2]
