ALFTP

ALFTP is an advanced FTP client that has many features and a unique Linux-like appearance.
The program has a nice sitemap system that allows you to create groups for your favorite FTP servers' login details, and it also provides the ability to make a quick connection.

In addition, the program allows you to connect to remote SFTP servers by providing their passphrase and their private key file.

The program offers advanced queue management that allows you to pause/stop/start your whole queue or some of its items. Transfer progress is viewable via a progress bar that tells you the status, percent done, total bytes free and transferred, time remaining and transfer speed. Both client and server explorers have a tree-like design resembling that of Microsoft Windows Explorer.

The program offers a wide set of options to facilitate your remote ftp browsing, initiating transfers by means of a single right click on any folder locally or remotely. A very important feature is a built-in FTP server which allows remote users to gain access to any directories of your choice, which allows them to download/upload any files. The built-in FTP server also provides the ability to choose which IP and port it should connect to, it also can be set to be read-only and you can password-protect it as well.
