Transferring files from my PC to my iPad is a big problem for me because it needs the iTunes to do it. I want to know that it is possible to use 8 pin adapter( like Apple's lightning micro USB adapter ) to which I can connect a pen drive for data transfer from pen drive to iPad? If yes please link the product, I want to buy it.
