+1. Camera memory cards are not designed nor meant for long-term storage. I'd really recommend copying all of your images to a hard disk drive, perhaps the one on your computer. Then, I'd purchase an inexpensive external HDD, they are very affordable, and re-copy the images to the external drive as a second back-up. Camera memory cards do fail over time.
If you remove all your images from your cards, you can then reformat them and use them for future photos, eliminating the need to buy new ones.
