This powerhouse FTP client takes some getting used to, but you'll be glad you gave it a chance. Don't be alarmed by the cramped, multipane Windows Explorer-like interface; you can customize the toolbars and windowpanes however you like.
With the Local Browser window visible, SmartFTP supports drag-and-drop transfers like those on basic FTP clients. But its real power lies deeper within its option menus, where you'll find CHMOD remote file-attribute modification, background file transfers, multiple FTP connections, passive-mode transfers, site-to-site transfers (FXP), and connections via proxy or SSL. Using the Global Queue window, you even can schedule downloads or uploads to more than one server.
SmartFTP may overwhelm beginners, but it's a natural for intermediates and up.
