Canon EOS R5 C VR Creator Kit with RF 5.2mm f/2.8 Dual Fisheye Lens - Manual (Page 542)

Transfer type/size
In [ JPEG size to trans. ], you can specify the size of images to transfer.
For example, to transfer smaller JPEGs when the camera is set to
record larger JPEGs to one card and smaller JPEGs to the other, set to
[
SmallerJPEG ].
In [ RAW+JPEG transfer ] or [ RAW+HEIF transfer ], you can specify
the type of images to transfer.
Note
When the camera is set to record RAW images to one card
and JPEGs or HEIFs to the other, specify which images to
transfer in the [
RAW+JPEG transfer ] or [ RAW+HEIF
transfer ] setting. Similarly, specify your transfer preference
when RAW+JPEG images or RAW+HEIF images are
simultaneously recorded to a single card.
Captured images are also stored on the card.
When images of the same size are recorded to both cards
simultaneously, images recorded to the card selected for [
Record/play ] or [ Play ] in [ : Record func+card/folder
sel. ] are given priority for transfer.
Transfer with SET
When set to [ Enable ], simply press < > to transfer the image
displayed. You can continue shooting still photos as usual while images
are being transferred.
