I need to transfer files using Windows Explorer from my PC to my 700T. When I connect my 700T to my laptop, which runs Windows 7, I get an option list on the laptop, one of which allows me to use Windows Explorer, and treat the 700T as an external drive. HOWEVER, when I connect my 700T to my desktop PC, via USB cable, which runs Windows XP, the file option list that comes up does Not list the Windows Explorer option. It would really be helpful to transfer files directly from the XP machine to the 700t, without having to go through my Windows 7 laptop. Can anyone give me an idea how I can get the XP desktop to give me the Windows Explorer file transfer option????
