Casio’s “.cam” file extension is created by Casio digital cameras whenever a picture is taken using a Casio digital camera. This file must be opened by the Casio photo software instead of any other kind of photo viewing software, such as “Windows Picture and Fax Viewer.” Converting the “.cam” file extension to the universal “.jpeg” extension allows it to be opened by many different kinds of photo viewing software, not just Casio’s.
