A digital picture viewer keychain is a great way to display photos for friends, families and clients. A digital frame can hold different numbers of photos, depending on the memory size. Picture keychains work like external hard drives. They hold a specific amount of data and display it on the screen. Two different formats are available: FAT32 and NTFS. Most of these devices come formatted with FAT32, which won't hold images over 4 GB. There is a simple way to reformat the device to NTFS, which stores files of all sizes.
Preparing the Device
Attach the digital picture viewer keychain to the computer via the USB port.
Back up all the files stored on the digital picture viewer keychain. Reformatting the device automatically erases anything stored on it. Save any files you want to keep to a folder on the computer.
Erase all files stored on the device. This step makes the formatting process smoother.
