a wrk file will contain all your midi data but no audio data. instead, it will point to audio files in your cakewalk wave data directory.

clean audio disk will delete any audio files in your cakewalk wave data directory that do not have corresponding wrk files.

bun files will contain everything, midi and wav.

you can clean audio disk in the middle of a project but it will clear your undo record, therefore you will not be able to undo anything that you did before you cleaned the disk.
