No. Lets say i have a 200 odd MB file in my cell & i want to transfer it to PC, or vice versa......i just use the "Share via Wifi direct" option on my cell & send it to PC, or just right click on the file on my PC, and send it to Cell via Wifi Direct. It can be really convenient. AirDroid is there, but then it requires u to take some steps before u can freely transfer stuff between Cell & PC.
