5. Don’t Fill Up a Card
This anecdotal tip goes back a long way, but it’s not commonly practiced. Refrain from filling up a memory card completely. It can lead to issues with certain types of cards.
6. Correct Way to Delete Images
A common mistake is to delete images one-by-one from an in-camera card. Doing that can shorten the card’s life. While cards are meant to be used for storage, the fewer times you add or remove data from the card, the better.
The correct way to delete files from a memory card is to wipe them all once you’ve uploaded those images to your computer. This deletes the files as a single event, not individual deletes.
7. Reformat your cards
Did you know you should periodically reformat your memory cards? It’s an excellent way to clean up your card. You should use your camera to reformat the card, but you should use the camera you plan to use with that card.
For example, let’s say you used it on a DSLR but want to switch to a mirrorless one. You should reformat the card on the mirrorless camera. Be sure to download your images before you reformat a card!
