See the Platform SDK documentation for more information. This parameter defaults to an empty string which causes the default verb to be executed (usually 'open'). |

Description
ShellExec is a wrapper for the Win32 API function ShellExecuteEx which alleviates some of the complexities of this function by providing defaults for some of its lesser used parameters. This function performs an action specified on a file which can be anything from executing the file to opening it using the associated editor.
