If you see the SD card on the right it has a little lever. If you have a lever or some kind of switch on it, you must push it the other way to unlock it so you can modify the files inside the card. Or if you don’t have a lever then you must right click on the file and go to properties and uncheck the box that says “Read Only.” This will enable you to modify the contents on the multimedia card.
