Tranfer problem from camera to computer.?

Never heard of a card reader that doesn't work. Try reseating the memory card in the reader and then making sure the reader is properly plugged into the USB port. If that doesn't work, try plugging the reader into a different USB port. USB ports can die. Finally, I would buy another card reader. Other than a card reader and plugging a USB cable from the camera to the computer, I know of no way to access the folder.
