FTP Commander Pro 7.90

The program lets you upload and download data or delete one or more files, including whole folders along with subdirectories. It can also automatically resume and complete file transfers, which for some reason, have been interrupted, or periodically attempt to connect with the FTP server if the pervious link was unsuccessful. Servers usually break off a connection automatically when the user is inactive for more than a specified period of time. The program includes a command that allows you to "keep connection," which means that retention prompts are periodically generated to maintain the connection. It also contains a passive file transfer mode. Server directories are sometimes hidden from view, which means that the directory modification option will be extremely helpful.
The properties window of the FTP server offers a number of highly convenient options: "Initial Directory on FTP Server". The service functions of the application include drag-and-pop, pop-up and a context sensitive menu, which can be called up by right-clicking the mouse. The program is compatible with Proxy, Firewall, Sockets 4, 4.5 and 5. The superb options of the program include: directory synchronization on local and remote access computers (for comparing modified or new files), a full range of keys and options to monitor command line control, manual input of FTP commands, etc. Its user-friendly interface becomes instantaneously apparent.
