to store in a SD card, you may get some error messages like memory card is
full. At this time, the first thing you may do is to delete some unimportant files from the card to free some space to store more
pictures. However, you may find you are unable to delete any file from the card
since you may get another error message there is a problem with the SD card. In
this situation, you cannot copy or move files from the SD card, either.
However, if you want to get back the important files on the card, you can
select a good way to perform the SD card lost data recovery.
