What I want to prevent is ringtones and pics from being seen twice by the system. So I wouldn't say see a ringtone called ring1 twice when picking a ringtone, and I wouldn't see a pic1 twice in gallery.
I know you can put a .nomedia in the folder you want to hide from the system, but can you do it in a single folder and it keeps sub folders also from being seen?
This is just a small example, but if I put a .nomedia under backup root, will that then hide ringtones, notifications, alarms, and pics with the single .nomedia file?
End result would be:
Will that work, or do I need a .nomedia in each folder?
