    file_name('field')
        This method returns the file name of the file uploaded through the
        form input field named 'field' - This file name does not reflect the
        local temporary filename of the uploaded file, but that for the file
        supplied by the client web browser.

    file_type('field')
        This method returns the file type of the file uploaded as specified
        by the filename extension - Please note that this does not
        necessarily reflect the nature of the file uploaded, but allows CGI
        scripts to perform cursory validation of the file type of the
        uploaded file.

    mime_magic('/path/to/mime.types')
        This method sets and/or returns the external magic mime types file
        to be used for the identification of files via the mime_type method.
        By default, MIME identification is based upon internal mime types
        defined within the File::MMagic module.

        See File::MMagic for further details.
