I'm not sure about \??, but see this excerpt from MSDN Re CreateFile:

lpFileName [in]
Pointer to a null-terminated string that specifies the name of the object
to create or open.

In the ANSI version of this function, the name is limited to MAX_PATH 
characters. To extend this limit to 32,767 wide characters, call the
Unicode version of the function and prepend "\\?\" to the path. For more
information, see Naming a File.

Windows 95/98/Me:  This string must not exceed MAX_PATH characters.
