If you are using a digital camera, it's a good idea to reformat your Memory Card after using it several times. Even though you delete unwanted images from the card it still keeps some of the information until it is over written. So if a digital camera starts giving you problems, the first thing to try is to reformat the Card. See your camera instructions for how to do this.
IMPORTANT: This will erase all information (and images) you have on this card. So, be sure you have moved the images you want to keep to a safe place first.
