How Do I Use The .bt Files?

[LuckyMist8]

In Particular, I'm Trying To Use The "MHS2 MOD.bt", Hoping It Has Something To Do With Converting The .mod Model Files In The Game
I Understand The .bt Stands For "Binary Template", So I Looked And Saw The "btBinaryRepackUnpack.bat" File In This Folder
But Running It Gives Me The [WinError 123] Error:

Traceback (most recent call last):
  File "D:\Documents Storage\3DS Stuff\MH Tools and Scripts master\btBinaryRepackUnpack.py", line 112, in <module>
    os.chdir(os.path.dirname(arg))
OSError: [WinError 123] The filename, directory name, or volume label syntax is incorrect: ''

I'm Not Sure What Part Of The Directory Path Could Be Causing The Error, I've Tried Moving The Working Folder To Different Places Including The Root Of My Drive But With No Luck

Is This "btBinaryRepackUnpack.bat" Batch File Supposed To Turn The .bt's Into Something Useful Or Am I Dumb??
I Really Want To Mess Around With The MHS2 Models 😭🙏
