 Protecting Images
You can protect all the images in a folder or on a card at one time.
When you select [All images in folder
or [All images on card] in [x1: 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].

 Protecting All Images in a Folder or on a Card
If you format the card (p.48), 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.269), only the protected images will 
remain. This is convenient when you want to erase unnecessary images 
all at once.
