Using a Computer
Individual photographed still images and other data are recorded on this camera as 
discrete blocks of data. Each such discrete block of data is referred to as a “file”. Files 
are grouped together into “folders”. Files and folders are automatically named so that 
they can be identified.
• For detailed information on the folder structure, see “Folder structure in memory” 
(page 60).
• The significance of the folder name and file name shown at the top right of the 
screen during still image or video playback is as follows:
E.g.) 100-0023: The 23rd file in the “100CASIO” folder
• The folder names and file names can be viewed on a computer.
• The number of folders and files that can be saved varies depending on the capacity 
of the memory card used.
