Please help me start up with tags

[MiniMe]

Dear Minimserver community,

I'm like fairly new to the MinimServer software and the possible joy that it brings,

Reason for me to step aboard is that I have uPnp streaming software that reads tags and is not so handy with my hierarchically sorting in folders. As such I look for a way to tag similarly, but I found quickly that how to set up proper sorting is for me a challenge.

What I have hierarchically in folders is the following:
Top : Genre (folder name)
Mid : Artist + Album (subfolder name)
Low : Track number (filenames in the subfolder)

When I came from Sonos I could click a Top level folder and play everything underneath. Now with the uPnp streaming I somehow can not yet play such Top level folder, but rather need to add Mid level one by one.

I know MinimServer can by tagging e.g. quickly show everything in a Genre, and display all items belonging to that Genre, however the sorting of files thereunder is A-Z of names that Minimserver has collected from both Filenames and Track Titles.

My question is, how do I tag and index in a way that is appropriate for the Top, Mid, Low levels in the further above example?

If any questions, please feel free to suggest, if already answered, could someone point me in the right direction? Any help I'd appreciate
