Many users, even professional photographers, often delete individual photos stored on the memory card directly from the camera's control menu.
However, this is not a good idea because in reality, the camera is a device designed specifically for capturing photos, not for smart data management on your memory card. Technically, deleting individual photos directly on the camera in the long run will corrupt the FAT table of the memory card. Therefore, refrain from doing this if you don't want your memory card to become scrap material.
Furthermore, memory cards are becoming increasingly affordable and with larger capacities, so there's no reason for you to delete photos to save space. When your card is running out of space, simply switch to another backup card and continue shooting instead of fussing over copying and deleting photos on the old card. Once you've copied all the photos from the card to your computer, format it to continue using it interchangeably with the remaining memory cards.

4. Do Not Remove Memory Card While Data is Being Read
If you insert a memory card into a camera or card reader and are copying data from it to your computer via USB cable, do not remove the card abruptly while the copying process is not complete. Doing so may interrupt the copying process, leading to data loss. It's best to wait until the signal light on the camera or card reader turns off for a few seconds before removing the card.
In principle, before removing USB-connected devices such as USB flash drives, external hard drives, card readers, mobile phones, etc., you need to close any open files on the computer and disconnect them from the system according to the correct procedure. This helps protect the devices, avoiding electrical shock situations that can cause damage or loss of data stored in them.

5. Use Card Reader to Copy Photos Instead of Using Connection Cable
In fact, using a connection cable to copy photos to other devices is still widely practiced by many because they don't have to spend extra money to buy a card reader. While connection cables are usually included by camera manufacturers when purchasing.
However, this habit adversely affects the camera's battery life, causing them to deteriorate faster when you use a USB cable to connect the camera to a computer. If you're in a place with limited power sources, insert the memory card into the card reader and then start copying to the computer instead of using a connection cable to save battery.
