i have a sony cybershot dsc w70 digital camera and i have a sony 2 gb memory card and when i take pictures and save them on to the sony memory card and then go back to veiw them i can see them fine but when i take some more and then try to veiw the photos on the card from the camera its says ( this folder is empty) . but when i save pictures to my cameras built in memory it saves them fine and lets me put them to the pc with no problem....?

i even switched the memory card at the store for another and same thing.

if the folder that the pictures are in gets renamed, it won't read the pics inside it.

put you card in an external adapter, copy pics to pc. insert card in camera and reformat.
