Opening a Session that Contains Fade FilesWhen opening a session created in a version of Pro Tools lower than 10.0, Pro Tools calculates and plays back all fades in real time. The “Fade Files” folder in the session folder is neither deleted nor used. Any rendered fades created in legacy sessions are calculated and played back in real time. Any new fades created in the session do not generate any new rendered fade files in the pre-existing “Fade Files” folder.
