3D-FTP is a lightning-fast FTP client with a multithreaded transfer engine providing file transfers that are up to 20 times faster. You can browse and change directories while transferring files in the background. Features such as bookmarks, direct remote editing, and directory synchronization make 3D-FTP the perfect tool for Webmasters. Also, the feature for calculating a directory's total size (including subdirectories) is great for keeping a Web site's total size below its limit.
Other features include antivirus scanning for downloaded files, the ability to print file listings, custom commands with macros, autoresume, autoreconnect, KeepAlive, a transfer queue, support for ratio sites, optional skins, and recurrant scheduling. You can extend 3D-FTP with API architecture and plug-ins (a free SDK and source code are available).
Version 7.0 adds new dialog-box color themes, antivirus scanning for each downloaded file, local bookmarks, and improved file management.
