Lost my save... Can I get it back with .hl1 .hl2 and .hl3

I had tried to save a map that I was setting up for a machinima and the game crashed. I get back on to find that my save was not there. This http://puu.sh/8eIK is the only thing that is in the save folder. Can I somehow use a program to compile these files to get my save back?
