Formatting the memory card
You can format the memory card in your device, for example, to free up memory. This means that you erase all data on the card.
All content on the memory card gets erased when you format it. Make sure you make backups of everything you want to save before formatting the memory card. To back up your content, you can copy it to your computer. For more information, refer to the chapter Connecting your device to a computer on page 104.
