Notes about the PPK 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 PPK file type is primarily associated with 'PuTTY'. PuTTY is a terminal emulator application which can act as a client for the SSH, Telnet, rlogin, and raw TCP computing protocols. The name PuTTY has no definitive meaning, though tty is the name for a terminal in the Unix tradition, usually held to be short for teletype.
