Everytme you re-insert the sd card it creates a new folder, so if you don't delete the first you will probably confuse the hand held camera and it will not be able to open the files in multiple folders. At least that is how my trail cam works. It shouldn't hurt anything it will just get to a point where your hand held will not be able to open the folders. If you just keep taking pics and re-setting your camera you will be able to use just the laser to set it up in no time. To eliminate all of the trouble with test pictures try setting it closer to home so you can go change cards in the middle of the week until you get good at aiming it. I did a lot of tasting in my yard with my dogs as targets, before I set them out. I got some really good shots of my lab digging in the flower bed!! Plus my first three sets to figure out the aiming on wild animals was only a 10 minute drive and 30 min hike, so I was able to go out and check every 3 days or so.
