Getting started
• The device supports the FAT and the exFAT file systems for memory cards. When
inserting a card formatted in a different file system, the device will ask to reformat
the card or will not recognize the card. To use the memory card, you must format it. If
your device cannot format or recognize the memory card, contact the memory card
manufacturer or a Samsung Service Center.
• Frequent writing and erasing of data shortens the lifespan of memory cards.
• When inserting a memory card into the device, the memory card's file directory
appears in the My Files → SD card folder.

device is transferring or accessing information, or right after transferring data. Doing
so can cause data to be corrupted or lost or cause damage to the external storage or
device. Samsung is not responsible for losses, including loss of data, resulting from the
misuse of external storage devices.
