Why does my camera say “Memory Full” when the SD card still has free space?

My older Casio Exilim EX-Z75 shows a “Memory Full” error when I try to take a photo, even though the 32GB SDHC card still has plenty of free space. I can usually delete one photo and then take one new shot, but after that the error comes back.

The card appears normal on a computer, with significant free capacity remaining, and I can even create files on it from the computer. The card currently has 2,377 photos/videos in the camera’s image folder.

Could this be a camera file-limit issue, a FAT32/directory limitation, or a sign that the SD card is starting to fail? What should I do to safely recover my photos and fix the problem?

I'm wondering if the issue isn't the space is full, but instead the File table is full. FAT32 is supposed to allow 65,534 files in a directory, but I've seen cases where the implementation of the hardware has more restrictive than the standard.

I have to ask, why do you want to carry over two thousand pictures in the camera? My tendency is to get the pictures onto a reliable hard-drive, and backed up to another media as quickly as possible. I've found that SD cards have a tendency to fail at the worst possible time, and are really easy to lose, so the sooner my images are on my computer, the better I feel.

Most likely causes are:

  1. A camera-side file/directory limit, even though the card still has free space. Some devices impose stricter limits than FAT32 itself.
  2. A failing SD card. Flash memory can develop bad blocks over time; the card may still look like it has free space on a computer, but writes from the camera can fail.

What to do:

  • Back up your photos immediately. Don’t keep shooting on the card.
  • If copying normally is unreliable, try copying images off carefully, even one at a time if needed.
  • After backup, replace the card. That’s the simplest and safest fix if the card is degrading.
  • It’s also good practice not to keep thousands of images on the card long-term; transfer and back them up regularly.

So yes, this could be either a camera implementation limit or card failure, but the practical answer is: recover the images first, then use a fresh SD card.
