About this mod

BSA Browser is an application to open and extract files from .BSA and .BA2 archives.

This was forked from Fallout Mod Manager's built-in BSA Browser. It was originally only for .BSA files hence the name BSA Browser. However it's been updated to support .BA2 files as well.

BSA Browser is open source and available from GitHub: BSA_Browser

Version History


Note: Previews are getting outdated, many Fallout 76 textures show incorrectly or don't work at all. Gonna look into updating, but it's not my code so not familiar with it yet

  • Implemented DX10 headers for Fallout 76. GIMP DDS support isn't great for Fallout 76, so you might wanna look into Photoshop or other tools
  • Changed how errors are handled during extraction. Extraction continues and a report is written in the destination
  • Updated Progress window
  • Fixed BA2 textures being extracted with null bytes at the end
  • Fixed being able to click extract while one is already active by blocking main window during


  • Fixed some textures causing invalid DDS header error


  • Very early Fallout 76 support
  • Added tool to compare archives. See what has been added, removed or changed
  • Removed "This archive is already opened" message. Bring window to front instead
  • Fixed rare decompress error with certain files (e.g. True Storms, Skyland)
