.SHG File Extension

What is an SHG file?
Bitmap image containing "hotspots" used by Microsoft WinHelp; certain areas of the image can be clicked to jump to other help topics; similar to a Web image that uses a .MAP file to define clickable areas.
SHG files are compiled by Windows Help File Compiler (hc.exe) and are referenced by Microsoft WinHelp. They should not be opened manually.
