I just went to put my pictures on my passport and I had the 2 slots set to overflow. I had 2 cards in the camera. I noticed 2 cards had about 8 duplicate pictures with the same numbers and the last day 2 cards had the same for about 35 pictures. I did not change the settings. Has that happened to anyone. Also some cards make a 2nd file and I did not do anything to get that. Do larger cards make a 2nd file after a certain amount of picutres?
