Notes about the PUP 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 PUP file type is primarily associated with 'Playstation' by Sony Corporation of America. Software updates may include security patches, new or revised settings and features and other items, which will change your current operating system. It is recommended that you always maintain your system to use the latest version of the system software.
