I am trying to make a hierarchical system of folders based on the Hornbostel–Sachs system (A hierarchical system of musical instruments). So far I have managed to pull a list of the internet.
Now I need to somehow make this list into folders and sub folders. First problem is, I have not exactly figured out how to make a folder with multiple sub folders.
I do not expect anyone to do the job for me. But some help on how to approach this would be much appreciated!
