Organizing my folders

[carlmart]

I wonder how can I do the following with Jellyfish.

Though years of dealing with media managers, using just my PC as server, with separate HDDs, folders and subfolders,
I got to the following organizing:

HDD A > Main Folder > Subfolders > Media

HDD B > Main Folder > Subfolders > Media 

... And so on.

How do I do to organize things in a similar way with Jellyfish?

Sometimes there are additional subfolders.

I couldn't figure how to do that with JF. The first time I set it up it mixed HDDs, folders, subfolders and media.

Thanks
