Hey! I'm really sorry if this is a common question, but i was not able to find an answer to this, was trying for like two hours... I want my pics on my android phone to be copied to a file on my PC, BUT when i delete them on my phone, i want them to NOT be deleted on my PC and also when i add something on my PC i want it to NOT be copied to my phone. Is this possible? If so, how? THANKS!!
