I made a stop-motion film for a school project. When I was done, I saved the file and ejected the usb flashdrive. The next morning I took a look at the file and there were no photos! I later discovered that this was because the sd card from the camera wasn't inserted in my computer. Is there any way to fix this? Can i save the file with the pictures still being there? And last question.....can i save the file to later be opened in another program (i.e. wmp)?
