          local system. Syntax
          object.ExtractFile( FileName, [MessagePart] ) Parameters
          
            FileNameA string which specifies the name of the file that the
            attachment will be written to. If the file does not exist, it will
            be created. If the file exists, it will be overwritten.MessagePartAn optional integer value that specifies the message part
            number that contains the file attachment. If this parameter is
            omitted, the method will extract the file attachment in the
            current message part. Return Value
          A value of zero is returned if the action was successful.
          Otherwise, a non-zero error code is returned which indicates the
          cause of the failure. Remarks
          The ExtractFile method writes the contents of a message
          part, typically a file attachment, to a file on the local system.
          This method will automatically decode any binary file
          attachments. To determine if the current message part contains a file 
          attachment, check the value of the Attachment property. See Also
