Nikon Coolpix 4500 to remove all pictures on the camera

Hi,
I have found the information you requested in a pdf format of the user manual. It is on page 128 of the user manual. It is very hard to tell you what button to push as I don't have one of those camera's in front of me. Here is a link for the user manual. Once to get to page 128 you should be able to see how to format your memory card. If you look at the pdf guide it is listed on the left side of the page under "playback menu" From there you can advance to page #128 and go from there. I sure hope this will help you get this fixed. Best wishes.
