This Powershell script will recurse all standard mod directories to include in a .achlist file to make packing BSA's with your mod easier. Just make sure you set Powershell to run scripts by running Set-ExecutionPolicy in Powershell. Next, edit the fields at the top of the file to make them relevant to your set up. Then, make sure that the only files in Data Files are the files you wish to pack with your mod. Lastly, run the script. This will output a file to the location you specified earlier, and then you can import that file into the CreationKit in the archive screen.
