If you are simply asking how to transfer files from a PC to a tablet I recomment using WiFi File Transfer (free version). I've done this via the wifi connection in my router as the desktop doesn't have wifi built in. I haven't tried this from a device with built in wifi, such as a laptop but it should be just as easy.
It's very simple to use and just works.
The only slight problem I had was, I think, a browser problem (you need to open up the tabletl via a browser). If you want to tranfer a whole folder, Firefox would not let me transfer a folder. I had to use Chrome to do that. But otherwise it's great - fast and easy.
