From South River Technologies:
WebDrive integrates FTP, WebDAV, SFTP or FrontPage servers into the Windows desktop. Your web server will appear as a network drive and your favorite applications can be used to edit and save files directly to the server. New A/V streaming allows video or music files to begin playing immediately rather than waiting for the download to finish. WebDrive also supports offline file synchronization. The WebDrive client includes proxy server support, a File Transfer Manager to automate backups and many advanced FTP features like resume interrupted download, Auto ASCII/Binary transfer selection and Unix file permission support. Version 7 may include unspecified updates, enhancements, or bug fixes.
