I was wondering how you actually send the files to the library eg. right click/ Send To, drag/ drop or some other way?
right-click/ Send To/ Music Library
with reference to the post
here, I found everything works fine as long as the two red highlighted fields contained the exact same path. If I truncate that path, or create an entirely different one on the same drive, MB will move the files correctly but the original naming template won't take over and rename them.
I understand now, for that to happen, the files have to be in the same 'to folder:' that the naming template references.
I think it was my understanding of how the naming templates were applied that was at fault, more than anything MB is doing.
