I purchased a 256MB pro stick duo for my sony cybershot and have filled it up 3 times. Each time I loaded the photos onto my PC and deleted them from the camera. This last time, the camera was filled after 17 pictures as if the last large bunch were still on there. When I loaded it into the computer, the 17 went and the 100 plus went onto my PC AGAIN... although I cannot find the pictures on the camera to delete them. It tells me NO Files in this folder, but only lets me put 17 pictures on, this happen to anyone else?
Make sure that you are putting the pictures into the memory card and not the internal memory of the camera. After downloading the pics from the card, make sure to reformat the card in the camera.
