gFTP

gFTP is a multithreaded File Transfer Protocol client program. It is most used on Unix-like systems, such as Linux, OS X/macOS, and Sony PlayStation 3. It includes both a graphical user interface (GUI), which utilizes the GTK+ graphical toolkit, and a command-line interface. gFTP has been translated into over 45 different languages. There is support for the FTP, FTPS (control connection only), HTTP, HTTPS, SFTP, and FSP protocols, as well as FTP and HTTP proxy server support and FXP file transfers (transferring files between two remote servers via FTP).

The GUI uses a double-paned layout, with the local filesystem in the left pane and the remote filesystem in the right pane. Below, there is a transfer queue that shows the real-time status of each queued or active file transfer. At the bottom is a message log, which displays the text commands and responses between gFTP and the remote server. Sites are stored in a hierarchical collection of bookmarks, though a site bar allows connections to unbookmarked sites.
