"Unknown File Type" -- Corruption Problem?

[Art Campbell]

To get it open, I'd try the undocumented "Heroic Open" command. I haven't
tried it in 9, so I'll assume it's there.

Open FM and create a new, empty file. Leave it open.
Type ESC, o, and Shift+h -- the Open File box should appear. If the file
opens, save it with a new name, and maybe save it as a MIF too.

****
If I were you, I'd MIF-wash all the files -- SaveAs MIF, open MIF, and
SaveAs .fm.

***
Also, I'd give serious consideration to transporting your files between
machines in a safer medium, such as Dropbox (www.getdropbox.com), which also
gives you great depth of backup files automatically.

Cheers,
Art
