I have just shot footage of videos and I can view them on my camera. Right now I don't have my USB cord because it broke, and it took over 2 months for it to get here the last timeI ordered a new one. So I am using my sd card, and whenever I insert it into my laptop, I says the file is empty. They are on my camera but not my sd card. Do my videosgoto a seperate file on my camera, and if so can I put them on mySD card?
