Either an Empty Variant, a string file name, an object IStream interface pointer or an object IStorage interface pointer. If an Empty Variant is given, then that Variant is filled with a Byte array (VT_UI1) holding the saved list information. If a file name is given, the file is saved as a simple ASCII text file into the given file name. If an IStorage is supplied, a stream named “Contents” is filled with the list information.
