Slowly I think I’m getting there. I put in the format \nssrvddf6\Downloads and this worked. Now it says the directory is empty and I need to add files. This is the place that the Naim Software gave me for storage on the web app.
I think I’ve not got something fundamental not quite right.
I think that’s where you dump them if your adding your own files not where you can get Roon to see them. You need to find the samba share path it might be nssrvddf6\Music according to the Manu. Sorry can’t help anymore than that as I dont have one.
