- 7-Zip Archiver
- Figure out where Steam is installed. Hopefully you installed it someplace outside of the default "Program Files" folder if you are using Vista or Windows 7 (due to UAC issues when modding)
Default for 64-bit systems --> C:\Program Files (x86)\Steam
Default for 32-bit systems --> C:\Program Files\Steam
My computer (hehehe) --> D:\Apps\Steam
- Figure out where you are going to store the unpacked files and make sure you have enough room to hold them.

- There is not an installer so you just need to extract the contents somewhere and run the program inside.
- Extract the BSAopt archive someplace such as C:\Apps\BSAopt\
- Be sure to run the program that matches your operating system. "BSAopt x64.exe" for 64-bit versions of Windows, "BSAopt x32.exe" for 32-bit versions.
- You can create a shortcut to the program if you want but odds are, you will not be using it again after extracting the BSA files.
Unpack BSA Files
- Start BSAOpt
- Click the 1st Browse button at the top
- Browse to Skyrim's Data folder <<Steam Folder>>\steamapps\common\Skyrim\Data
- Double-click on a BSA such as "Skyrim - Meshes.bsa" and wait for it to load
- Select *.* from the dropdown selection and click the Apply button next to it
- Click the green checkmark button to select all files
- Click the 2nd Browse button at the bottom
- Browse to the folder you wish to store the extracted files and click the "Use Folder" button and wait for it to skim through the archive
- Click the Convert button at the bottom-right corner and wait for it to process all the files
- To extract more at this point, simply repeat the above steps
It would be a good idea to configure NifSkope to look in the folder where you extracted the textures. When you open a NIF file that uses textures that shipped with the game, NifSkope will not be able to look inside a BSA to show you the textures, you will need to re-direct it to look in your "out" folder.
- Start NifSkope
- On the menu, click Render, then Settings
- On the Rendering tab, click the Add Folder button to add a new path to the texture search path.
- With "Choose a folder" selected, click the "Folder" button below it and select the folder where you extracted the "Skyrim - Textures.bsa" file. Example: E:\Games\Skyrim\out
- Close the Settings dialog box
- Now when you open one of the NIF models in your "out" folder, NifSkope should be able to find and apply the texture to the model (instead of looking at a white object)
Example: Open E:\Games\Skyrim\Out\Meshes\Weapons\glass\glasssword.nif
