This memory card is protected

To delete all the photos on your memory card, the easiest way is to format it. See your manual for details.

If you require further assistance, please add a comment to this question and specify the model of your Samsung digital camera.

The protect function allows a user to protect a picture from accidental deletion. To unprotect a picture on your camera, scroll to the protected picture that you want to delete, then press the Menu button (the button to the right of the Play button.) Scroll down the menu and you should come to an option that allows you to Protect/Unprotect the picture. Since your picture is currently protected, deselect that option. You should then be able to delete the picture normally.

Alternatively, you could also format the memory card, however this deletes ALL photos and data you have on the memory card. If you are trying to completely clear the memory, this is the best way. After turning on your camera, simply press the Menu button, scroll to Setup, then scroll down to Format. Select Format, it will ask you if you want to format the memory card, or the camera's built-in memory. Format whichever one you want to clear, if you are using a memory card then your pictures are stored on the memory card. It will take a few seconds to format.

Hope this helps.

The instructions for protecting/unprotecting images are in the "Protecting images" section of the manual (page 98 in my copy).

The best way to delete all photos on a memory card is to format the memory card. This should be done each time you finish transferring your pictures to a computer, as FixYa is full of people asking how to retrieve pictures from cards that haven't been recently formatted. Refer to the "Formatting Memory Cards" section of the manual (page 22 in my copy).

If you need a manual, you can download one from the manufacturer's web site at

"Protecting Photographs from Deletion

In full-frame, zoom, and thumbnail playback, the button can be used to protect photographs

from accidental deletion. Protected files can not be deleted using the button or

the Delete option in the playback menu, and have DOS "read-only" status when viewed on

a Windows computer. Note that protected files will be deleted when the memory card is
formatted"

Easy solution:

1) Put the sd card into your computer
2) Copy all the photos to your computer. User Windows Explorer to just drag the folders from the card.
3) Format the card

If you insist on having the photos back on the card, then just copy them back to the card using Windows Explorer reversing step 2.

Take your memory card out of the camera and switch the position of the little "lock" tab. That should fix it and you can start saving images.

Some SD cards have a tiny "write protect" switch on the side. Might you have knowcked that? I would try taking the card out & seeing if you have one.

Otherwise, you can always look for the manual on the manufacturer's web site:

Memory full means, if you have inserted a memory card, it is full and you need to delete or upload photos to your PC. If it is internal memory (*meaning you did not put a memory card in) then hook it up into your computer and upload the images. You can usually delete them by pushing the little green play button and then choosing delete all/one

Always format the memory card on the camera, using the menu or shortcut key combination, not on the computer. Formatting from Windows is not the same thing.
Have you done a format from the camera itself?
Is the memory card write-protected accidentally?

There is a switch on the memory card, you just have to slide it upward.
