Keil files for project

I bought some Silicon Labs C8051 boards, equipment, and PC for someone recently and am
going through a computer now. I found some SW - created by Silicon Labs for the C8051F340
board I'm playing with now. It doesn't look like the guy ever compiled any of this code.

There is a Keil uVision3 compiler installed - version 3.50 it says. In several of the
source code directories I find files that I suspect are for the Keil compiler/IDE perhaps.

They have extensions of .wsp and .omf. I've tried to run the uVision IDE and open these
files - but it doesn't seem to work with them.

Does uVision3 create or use files with these extensions, as a project file of some sort,
and if so, how do I open them ?

Thanks
