Cubase legacy file extensions?

Is there a list somewhere of all the legacy file extensions, what their function is and which Cubase versions they are valid with?

While going through a search to learn how to convert *.prt files, I’ve become aware of this issue.

I also have some files I acquired off the net after I bought some legacy hardware. Those files are puportedly midi device panels with an extension of *.dev (which I assume stands for devices?). I also found some with *.mix.
