I'm not sure about how the ATN scopes save their files onto the memory cards,
but I know that with several of my high end digital cameras, the files are separated.
Ex: When viewing the contents of my memory cards,
there will be several different sub-folders. Depending on how I've set the cams up to save,
photos and videos can all be saved to one folder,
photos can be saved to one folder and videos can be saved to another folder.
Then I noticed that even within the folder where videos are supposed to be,
sometimes they're not.. they somehow save in yet another folder.
So that said, double check the contents of every folder that appears on your card.
Process of elimination.
