You can create a Collection (File > Manage Collections) that only has those folders that you want included. Collections will have the Files to Edit node available for just that Collection.

Sorry for delay. Belated happy new year.
Music > Files To Edit > Duplicate Titles.

Which Duplicates feature are you using?

I am very new to MM and not finding it that intuitive at moment but I am succeeding in doing things to do so all good.
Rightho having managed to create a playlist on my NAS which took me a while, can anyone help me on how to filter my duplicate search so it only searches on a particular folder and playlist. Not sure if you can search on playlist in this way.
Merry Christmas to those who help me... :wink:
