I have different base folders that everything branches out from. i.e.
Music_CD
Music_HD_PCM
Music_DSD
And under each I have a folder for source origin. And under that I have the standard Artist/Album/Track
So, for example
Music_CD
------Fleetwood Mac
--------------------Rumors
--------------------Tusk
--------------------Mystery to Me
--------------------Mirage
Music_HD_PCM
------HDTRACKS
----------------------Fleetwood Mac
-------------------------------------Rumors (24/96)
------ProStudioMasters
----------------------Fleetwood Mac
------------------------------------Tusk (24/192)
Music_DSD
------Acoustic Audio
----------------------Fleetwood Mac
-------------------------------------Rumors (DSD64)
------SACD
----------------------Fleetwood Mac
-------------------------------------Mirage (DSD64)
So, Fleetwood Mac files might be under the different sub-folders, but, in Roon, it is all compiled together. The text in the parentheses will be added as Version Info in Roon.
