I just use the convention, for folder hierarchy, established in the early Octatrack sound packs that I bought like Hell Bent On Circuits.
Inside the Hell Bent On Circuits folder, there is another folder with the same name, and it has a bunch of .work and .strd files. Some start with “arr”, others start with “bank”. Then there are markers and project files. I don’t know for sure which are pattern or part files.
The other folder inside the main sound pack folder is the AUDIO folder, which has a hierarchy of samples.
