$link
->Save([file
])
Saves the content of the shortcut object into the file named file.
If file is omitted, the filename is taken from the File
property
of the object (which, if not changed, is the name of the last Load
ed
file).
If no file was loaded and the File
property doesn't contain a
valid filename,
the method returns undef
, which is also returned on error.
A true value is returned if everything was successful.
