with all the digital cameras I have every one of them counts each picture and labels it, Such as 001, 002, 003, 004 and so on but never restarts the count over again. I have noticed that when I use my Phantom Pro V 2, the camera doesn't keep counting higher numbers but starts over again each time I take it out . so when I place them in a folder it always asks the question do I want to copy over the picture that is already in the folder. It would be a different photo using the same # which means I now have to rename them each time I put them in the folder. Not sure if I explained the problem correctly.
