If you google ".fab file extension" it return lots of links that may help identify the software.
As you have the placements you could number the nodes and use an autorouter to re-layout the board, unless it must be identical to the original layout. If you have an original board you could X ray it to identify the routing.

Although this is not fitting the homebrew PCB category, many experienced
guys are hanging out here and hopefully someone have some helpful
suggestions:
We have to manufacture a 10 year design, an 8 layer board with only partial
documentation. I have found Pick & Place info and some Gerbers but only the
stencils, solder mask, drill CNC, and legends but not the traces on the
layers.
There is a very large file, 3.8MB with a .FAB extension that appears to have
lots of info in it. I suspect it is the native format of the CAD program
used.
Any suggestions to what the native program was?
Any suggestions how to import it into Protel?
Thanks in advance for your suggestions.
