Micro SD memory cards are external memory units that hold data and files. Memory cards are very useful in storing information for you to travel with or to take from one computer to another. Micro SD memory cards are also used in many different types of digital cameras to store pictures. As the memory card becomes full, instead of purchasing a new Micro SD card, you can reformat the card. Reformatting the card will erase all contents stored on the card.

    Highlight "Format" and click once. This will initiate the format process and bring up a box with the memory card information. Click "Format." Allow the system to reformat the card completely. Once finished, you will be prompted to remove the card. You have now reformatted the card, and it is ready for use.
