Unlike most FTP applications, FTP Desktop integrates into Windows Explorer, so you don't have to learn an entirely new user interface. Once you've configured the program with the address (and username and password, if necessary) of the FTP server, simply click the server's name in the left Explorer pane to connect, and then navigate as you would do with any other drive on the computer. The free version of the program permits you to make 300 FTP connections before it stops working; some users may never reach that number, but a busy Webmaster might do that in a week.
In fact, FTP Desktop is so intuitive and easy to use, you might come to find it invaluable, especially if you're a Webmaster. The only downside of the program is its age, and the fact that it hasn't been updated since 2004, a few months after Microsoft released Windows XP Service Pack 2. Windows Vista users might not be able to use the software.
