iUSB works with the CF3 MFi device to provide one-touch photo and video backup. With the simple, one-touch backup button, all photos and videos are backed up onto the external device. With the option to select specific photos and videos, the user can backup only the images and videos selected. The "use camera" feature allows photos and videos to be shot and saved directly to the external MFi storage hardware. The view files features allows the user to view the files saved on the external MFi device
