Notes about the PK file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to
scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
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.
