Bc2000 (for the BCF2000 & BCR2000)

Hi All,
my roommate just informed me that I can control my DW6000 with my BCR2000. 
I downloaded to files (DW6000.BC2 and DW6000.SYX) from this group in hopes of doing this but I'm at a stand still due to my lack of know-how.
Can anyone tell me what I need to do with these files, my Mac won't recognize them.
Sorry if this is vague, but it's all I can say at this point.

thanks
