My SD card has a load of pics and music on it from when I had my Galaxy S2, When I put it in my lumia it shows all the content fine no issues, when I connect it to the PC it shows Windows Phone in explorer, when I go into it it only shows the contents of the phone which is nothing as all my content is on my SD card. If I want to use media player to add more music its gonna end up on the phone not the SD card, how do I add to the SD card?
