I've lost the panel file!

I changed out my pc back in March and from that time onwards I cannot access the panel file that contains all the data need to create the panel. The panel appears ok but I can't access the file to make additions such as adding panel icons to access things that aren't there. Panel.cfg is there and everything works but I know there should be another file. This applies to every aircraft in the stable. I can't remember the name of the file which should be in the "Panel" folder so it has to be hidden somewhere.

I'm operating Windows 7 so finding the file may not be so easy as in XP
