Easiest way would be to create a new folder on the desktop of a computer, plug the card in using a USB reader/writer if your PC doesn’t have a card slot, drag the data from the card into it, and then plug in the new card and drag the data to it from the open folder. Don’t just put the folder onto the new card, but take the individual files and folders from the ‘new folder’ on your desktop directly to the new card :-)
