Protecting images
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 [
3
: Protect
images] , all the images in the folder or on
the card will be protected.
To cancel the selection, select [Unprotect
all images in folder] or [Unprotect all
images on card] .
If the search conditions are set with [
3
: Set image search conditions]
( = 385), the display will change to [All found images] and [Unprotect all
found] .
If you select [All found images] , all the
images fi ltered by the search conditions will
be protected.
If you select [Unprotect all found] , the
protection of all the fi ltered images will be
canceled.
o If you format the card ( = 511), the protected images will also be erased.
o Once an image is protected, it cannot be erased by the camera’s erase
function. To erase a protected image, you must fi rst cancel the protection.
o If you erase all the images ( = 353), only the protected images will remain.
This is convenient when you want to erase all unnecessary images at once.
