Thanks for reply. I am not using Kodi to play files, but instead to play movies from Repositories.Why on earth one should use the absurd kodi to do a simple thing like playing a file? Even if BH is not simple like OBH at playing files in any subfolder or external devices, you still have the chance on installing EMC (Enhanced Movie Center) that makes possible to browse folders and devices.
Kodi is the office for complication of simple affairs (in my opinion).
If, instean, you'll try OBH, EMC is not even so needed to play files wherever they are located.
