Using Two Memory Cards
When two memory cards are inserted in the camera, you can
choose one as the primary card using the Primary slot selection
item in the shooting menu. Select XQD card slot to designate the
card in the XQD card slot as the primary card, CF card slot to
choose the CompactFlash card. The roles played by the primary
and secondary cards can be chosen using the Secondary slot
function option in the shooting menu. Choose from Overflow
(the secondary card is used only when the primary card is full),
Backup (each picture is recorded to both the primary and
secondary card), and RAW primary, JPEG secondary (as for
Backup, except that the NEF/RAW copies of photos recorded at
settings of NEF/RAW + JPEG are recorded only to the primary card
and the JPEG copies only to the secondary card).

recorded to the memory card in the primary slot.
