Family Tree for Windows 95

A friend of mine has had a long break from his genealogy work. He
still has his datafiles from many years back, but not the software
that he used.

He used something called "Family Tree", running under Windows 95 at
that time. The files he still have is named DOS***PT.001, DOS***PT.002
asf.

I don't expect a lot of people to have or to know this "Family Tree"
software, but if anyone can help I would be most grateful.

regards,
Jan
