I keep hearing about the perils of bundle files. Nah.....
In amost 20 years of using them (*.bun as well as *.cwb files) I’ve had ONE file get corrupted. That’s it. ALL my projects are backed up twice (in two different physical locations on two different hard drives) and I’ve not had any issues since my one corrupted file - which I think was over ten years ago when we were using whatever version of Cakewalk/Sonar we were using then.
