I had to open new folders on this card after about every 40 or so images.
If you meant to make the folders regardless, I'm not sure about this. However, if you 'had' to open new folders in order to keep writing to the card, I think a simple format of your card should fix it. I had some 8gb usb sticks that had a memory limitation in windows. I could not use the full 8gb when copying images onto it. I researched some tech forums and found I needed to format the usb stick. After that I could put all my images onto the root of the usb drive.
