bluetooth and cell phone moto u9

Hi everybody I have a problem copying file on my moto U9 cell phone through the bluetooth.

The connection between the pc and the phone works well and I can see a mounted device called “MOTO U9”.

If I open this device the position in


and there are a few directory in it.

If I try to explore the directory “Memory card” (wich I suppose is the memory with my music inside) an error message pop up:

“Couldn’t parse the incoming data”

Any idea?

Thank you
