Function Description

This subfunction uses the 'Explore' method of the Shell Object to open either a directory or special folder represented by a ShellSpecialFolderConstants Enumeration (a reference for which may be found here) in Windows Explorer.

The function will return T if the folder is opened successfully, else nil if either the folder is not valid, or if the method returned an error during execution.

The ShellSpecialFolderConstants Enumeration may be used to open special folders (such as Fonts, Program Files etc); note that the hexadecimal value for the enumeration found in the aforementioned reference should be converted to decimal before being supplied to the function.
