I have a client that just got back from LA recording their album and
the files that they have returned with will not open. They had no
extensions at all. 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.

Thanks in advance
