@winnielinnie
library was created by plex.
I thought that by creating a separate child data set under container apps that it would then no longer be in the media folder.
Anyway I will still have to point plex to the media folder.
What I want is the library in a separate folder, not between the media files.
Is that possible?
Just turned everything back for a while now.
Can't hobby any further at the moment

Thanks for your help Winnie !
