Answer 1

In addition to the answers already provided, you can accomplish this by calling the command line programs "ASSOC" and "FTYPE". FTYPE associates a file type with a program. ASSOC associates a file extension with the file type specified through FTYPE. For example:

FTYPE SMCFile="C:\some_path\SMCProgram.exe" -some_option %1 %*
ASSOC .smc=SMCFile

This will make the necessary entries in the registry. For more information, type ASSOC /? or FTYPE /? at the command prompt.
