Secure Digital (SD) cards are designed as a flash storage device, offering quick data transfer with low power requirements. SD cards are used in digital cameras, video cameras, MP3 players, smart phones and other devices. The cards are widely compatible across many operating systems, and you can manage your files from most computers by inserting the card into the computer. If your card is cluttered with too many files, or if you want to get rid of sensitive information on the card, you can reset it. Formatting the SD card deletes existing data and wipes the card clean.
