K Protecting Images 3 Protecting All Images in a Folder or on a Card You can protect all the images in a folder or on a card at once. When you select [All images in folder] or [All images on card] in [31: Protect images], all the images in the folder or on the card will be protected. To cancel the image protection, select [Unprotect all images in folder] or [Unprotect all images on card]. If you format the card (p.67), the protected images will also be erased. Movies can also be protected. Once an image is protected, it cannot be erased by the camera's erase function. To erase a protected image, you must first cancel the protection. If you erase all the images (p.360), only the protected images will remain. This is convenient when you want to erase unnecessary images all at once. When [All images on card] or [Unprotect all images on card] is selected, the images will be protected or unprotected on the card selected for [Record/play] or [Playback] under [51: Record func+card/folder sel.]. 335
