I think .BAK is a backup file extension which ProTools can auto-generate
if you have that preference set. It usually creates back-up files of
the session only, though. I don't think it auto-saves audio files. I
could be completely wrong about all of this info, though....

I had to add .pts to the session files to get them
to open, and after looking at the audio files it looks like they are
all labeled as .BAK files. Is anyone familiar with these files and do
you have any suggestions as to what to do? I really don't want to have
to rename all of the files as .aif so that they open.
