Some USB cords to the computer are only for charging, have only the + and - lines in them. This is for security when using a USB port on any public charging station that is a computer from being able to access your data. You need to be sure you have a 4 wire cable that also allows data flow from the phone in order to access and copy the data on it.
I just tried to transfer pictures from my Smartphone to my computer. Supposedly transferred, but can not find now that it is done. Are they in the DCIM folder I can't access? My Phone connected to my computer states nothing to transfer. so they must be on my computer. But I've spent hours looking around for help and tips. Nothing makes any sense. Kris
