Let me tell you an easier way to do it when it says "Card Full". Press and hold "Menu". Then, push the "Reset" button, but, continue to hold the menu until the camera re-starts. The camera will start in menu screen. What you did is, by the time the processor of the camera wakes up to give you the "Card Full" message, it is too late. You were faster than the camera by holding down the menu button. So, the camera starts in menu screen and no more "Card Full" message. Then, while you are on menu screen, press menu again to take you to the second menu screen where the word "Format" is located. Go ahead and format the card through the camera. Put a note how to do it because this problem will be there every time you format your card through Windows 10. Until of course they come up with an update.
