Notes about the CS4 file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The CS4 file type is primarily associated with 'CaptureShop' by Sinar. File naming can be automatic and sequential. For example: Name "FIRST_SET", Number "10", Digits "3" and Append Extension on will number your images "FIRST_SET010.CS1", "FIRST_SETt011.CS1", "FIRST_SET012.CS1" and so on when taking 1-shots or the same with .CS4 if taking 4-shots.
