Nikon D5300 transfer files between SD cards
During my last trip I took several dozens videos with my Nikon D5300, but they are on different SD cards because of the space.
I want to display them on my tv using the HDMI cable directly from the camera, because if I view them through my computer they are a bit choppy (not too much but still noticeable). However because they are on different SD cards I want to put all videos on 1 single SD card so I don't need to change cards during the viewing of the videos.
However if I simply copy the videos of one card to the other using my computer, the camera doesn't recognize the transferred videos. It only finds the videos that were originally recorded on the SD card.
Anyone know how I can transfer videos so that the camera recognizes them and can display them on the tv?
Thanks in advance!
