Subject: Unusual File Compression Method

I am trying uncompress some files I obtained from SIMTEL-20 that are
of the form: 

*.?Y?

Can anyone indicate what this form is and what I need to get to
uncompress it and where?  I am already familiar with *.LBR, *.?Q?,
*.?Z?, and *.ARK, but this one has me stumped.

Thanks,
Ken Lyons
