Use WiFi to transfer files
How to use Wi-Fi to transfer files between an Android tablet and a PC? Using your browser, transfer files over a WiFi network between your PC and tablet. This method uses a Wi-Fi network and connection. First, you must have a WiFi network where both the tablet PC and the PC are connected.
There are 3rd party applications that will use WiFi to transfer files between an Android tablet and a PC. I recommend AirDroid, which is a free app from Google Play or Amazon Apps.
After you download and install the app, it will give you directions on how to use it. Instructions such as what IP address to use, and a password to use to connect the devices.
Another app that seems to work well is WiFi File Explorer, there are other apps also available on Google Play.
This method is not as reliable as using the USB method, however, several users have had success with this. Read about transferring files using an USB cable.
