What have you tried? What was the result?

You may have to open them in a middle version first, like 2008.

This is the problem: All these files were maked on Finale 2.62 and 3.0, about 1997 or 98. More than 20 years ago!!!. They are scores of traditional music, for to publich in a book. They are a lot, and I was working for many years. In adition, I did save them into floppys. So I had to buy a floppys reader compatible whith Mac. I could open the floppys, but, unfortunately, no the Finale files. You say that first I use the Finale 2008. I have the Finale 2007, but I got it, neither .... 

What can I do?.

Thak you very much to help me Mike Rosen!!!

My oldest files still open and I go back to the beginning. This is something that Support may help with. Use the Submit a request link at the top of the page.
