Audition 2025 not opening pkf files

[SVenner3212]

One of my clients sent me some of his audio files in pkf format to work on a project for him. I have Audition 2025 however when I try to open the file, it cannot find the file. When I look at the file types that Audition can open, that is not one of the formats. 

From everything I read online and in the Discussion forums, I cannot find anything that I can do to open these files. I read that you're not able to convert the pkf files to any other format - is this true? Can someone suggest anything?

I'm afraid that .pkf files don't contain any audio at all. Their only purpose was to store the visual information about what a file looked like when the waveform was displayed. Their purpose was to help open the actual audio file more quickly - simply by removing the need for the file to regenerate that information. Generally they are stored with their associated wav files and can only be used in conjunction with them.

Thank you for this information.
