SFK file extension - Sony audio waveform visualisation data
What is sfk file? How to open sfk files?
File type specification:
File extension sfk is mainly related to a special type of temporary files created by Sony programs, such as ACID, SoundForge or Vegas.
The typical .sfk file contains visual data that help the program draw the audio waveform on the screen. Meant to speedup the process.
It appears that this file is mainly generated automatically when a song is put into a projects or when an audio file is opened.
For example CD Architect will always create an .sfk file automatically when you put a song into a project, whilst Sound Forge creates .sfk files when you open a file in "Direct Mode" and also creates these files when you save a .wav file and answer Yes to "Would you like to reopen the file in Direct Mode?"
You should be able to find some option menu that clears and deletes these files when the program is closed, but you can always delete them manually.
