Notes about the PK 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 PK file type is primarily associated with 'Audition' by Adobe Systems Incorporated. Adobe Systems Incorporated acquired the technology assets of Syntrillium Software in May 2003. On August 18th, 2003 Adobe released a rebranded version of Cool Edit Pro 2.1 as Adobe Audition software. Audition/Cool Edit creates .PK files which are known as Peak Files. Peak files store data associated with the graphical representation of audio data (i.e., Waveform diagram). Audition/Cool Edit has the option to disable the creation of these files, however this may slow loading, saving and re-drawing of graphical data. These files can safely be deleted and will not effect the original audio data in any way.
