Think you'll have to dig in the registry to find the open command

(1) under HKEY_CLASSES_ROOT look for dot + extension

eg pdf becomes .pdf

The (default) on the right gives you the name of the application

(2) under HKEY_CLASSES_ROOT\nameOfApplication\Shell\Open\Command you will find the command line

See attached example
