I am trying to figure out how to transfer data from PC to K1 tablet (and vice versa). K1 has no USB port that I can find. There is an app called LeTools that supposedly lets you do this via WIFI, but it isn't installed on my tablet, and I can't find any downloads for it. There is a download to install LeTools on a PC, which I have done, but it needs an app installed on the tablet to communicate with. I tried LeNovo software support but they seem oblivious. Any suggestions would be appreciated.
