Is there a way how I can browse through NAS folders and directly playing files from there without having to make the folders favorites?
Not 100% sure but I think you can make the root directory a favorite and then you have access to all of the drive. I’m not where I can check right now but I think you can.
I know that this is possible. But unlike other favorites, the (NAS) root directory cannot be password protected. Therefore, it is not really a solution for me.
Then set up a top level folder for “Media” for all videos that you can sub divide inside like you wish and make that “Media” folder a favorite.
That’s about the only choices you have I believe.
