020 * <p>High level API for processing file uploads.</p>
021 *
022 * <p>This class handles multiple files per single HTML widget, sent using
023 * <code>multipart/mixed</code> encoding type, as specified by
024 * <a href="http://www.ietf.org/rfc/rfc1867.txt">RFC 1867</a>.  Use {@link

026 * of {@link org.apache.commons.fileupload.FileItem FileItems} associated
027 * with a given HTML widget.</p>
028 *
029 * <p>How the data for individual parts is stored is determined by the factory
030 * used to create them; a given part may be in memory, on disk, or somewhere
031 * else.</p>
