Folders/shares excluded from media scan

Thanks for your reply.

The thread I mentioned above (Indexing / Scanning Media - Myth or True - #4 by Parambir_Singh) says “The Twonky DLNA server media scan and the MyCloud media scan/thumbnail are entirely distinct activities”. Am I correct in thinking that the Twonky scan is to support the delivery of media (videos, music, etc) to devices on the local network whereas the other scan is to create thumbnails to support remote access over the internet? It’s useful to know that the Twonky scan can be controlled but I think it’s important for me to understand whether, and if so how, I can control how many files are subjected to the other scan.
