.drf file extensions -- HOW TO OPEN?

[Yee-Haw_400EX]

Does anyone know what program to use to open .drf file extensions? All of my dyno curves are saved as this type of file.

im not sure what uses that file type but i got a bunch of programs and im sure something will open so if you want to you can email them to me at bauman43@me.com and if i get them open ill save them as a .jpg file or something similar.
