Cannot find instructions in manual for Nikon Coolpix S210 on how to delete ALL photos from memory disk. It will let me delete one at a time but I want to wipe the memory card clean. Thanks for any and all help.

These instructions are from the Instruction Manual of the Coolpix S 210 and need to be carried out within the Set-Up Menu.

Refer Page 19:

Removing Memory Cards
Before removing memory cards, turn the camera off
and confirm that the power-on lamp is off. Open the
battery-chamber/memory card slot cover and press the
card in 1 to partially eject the card 2. The card can
then be removed by hand.
B Formatting Memory Cards
If the message at right is displayed, the memory card must be
formatted before use (A110). Note that formatting permanently
deletes all pictures and other data on the memory card. Be sure
to make copies of any pictures you wish to keep before formatting
the memory card.
Use the multi selector to choose Yes and press k. The
confirmation dialog will be displayed. To start formatting, choose
Format and press k.
• Do not turn the camera off or open the battery-chamber/memory card slot cover until
formatting is complete.
• The first time you insert the memory cards used in other devices into the COOLPIX S210, be sure to
format them using this camera (A110).


Refer Pg 110:

 Format Memory/m Format Card
Use this option to format the internal memory or a memory card.
Formatting the Internal Memory
To format the internal memory, remove the memory
card from the camera.
The Format memory option appears in the setup
menu.
Formatting a Memory Card
When the memory card is inserted in the camera, the
Format card option appears in the setup menu.

Hope this helps
