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

of external storage devices.
