Notes about the CCO 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 CCO file type is primarily associated with 'Command Console' by DigitallyCreated. Command Console is a program that allows you to launch programs, open directories, open documents, and other assorted tasks all from the Run dialog using short code. You can create custom Command Files that open programs, documents, etc. and run these commands from the Run dialog.
