It depends on your camera software. With my olympus camera using camedia software, there was a setting to only download the new photos, my sony software didn't have that option, I notice with my new canon, it downloads by dates to separate files. I'd check the help feature with your program.
Reply:Just stop it doing it automatically and instead select only those you want, and use the lefthand pane of the window to copy and paste where you want.
