Tips for Erasing Images Using [PROTECT] and [ERASE ALL]

For example, if you have 100 recorded images and you only want to keep 5 or 6 of them, using [ERASE] or 
[SELECT AND ERASE] to erase individual images can be very time-consuming.
In a situation like this, where you have a large number of recorded images and you only want to keep a few 
of them, you can accomplish it in just a few steps using [PROTECT] and [ERASE ALL].

1

First protect the images you want to keep. ( "[U] Protecting Images from 
Accidental Erasing (PROTECT)"  Æ p.107)

2

Then erase all the images. ( "Erasing all the images (ERASE ALL)"  Æ p.106)
All the unprotected images are erased, leaving just the protected images behind.
