What am I supposed to do?

[armaxd]

I got a problem which I tried solving but I couldn't figure it out.

 

Instead of 'Meshes' being a folder, its a BSA file, i tried using BSOpt to convert it into a folder, but when I do that it just converts the 'Meshes' Bsa into a Bsa called 'out' what am I doing wrong, or is there some other way of doing it?

I use this to extract BSA.
