I'm test driving the new Premiere and noticed that it does not create .cfa files when importing video. Only creates *.pek files and that's it.
I can't say that I am not happy about it because it does save a ton of cache space, however, I want to find out if anything is broken or if there is a setting which controls it. I can still see waveforms and hear audio, however, I am just puzzled as earlier versions did create .cfa files and I have a ton of free space in the media cache folder.
.cfa files are only created when importing compressed audio. It does this to replace that audio with an “uncompressed” version of it as a helper file. This will happen for instance by importing mp3 or m4a files or when importing an mp4 from a camera like a gopro which records compressed AAC as its audio codec. It will not happen with uncompressed linear pcm audio in for instance AIFF or WAV files or a quicktime ProRes file which often also has linear pcm audio.
