This parameter is optional. If set, the downloaded file will be copied to the given location. The whole target path must be given, including the file name, and the parent directory must already exist. If running from an interactive session, a relative path will be relative to the folder containing the macro; when running in batch mode, the path will be relative to where the metview command was run from.
