AirDroid – Control Your Android Device from Your Computer
AirDroid is an Android app that you can use to control your Android device(s) from your computer. Once you have the app configured on your Android device and on your computer you will be able to wirelessly transfer files between your desktop and your Android device. You can also access all of the contacts stored on your Android device. Just about any other file or function that you would like access on your tablet or phone from your computer, you can.
