Having the ability to transfer files from computer to FTP server or vice-versa is great. Wouldn't it be nice if you could just edit a file that's on the FTP server though, without having to download it? With FileZilla that's not a problem. You can view graphics files and edit text files right on your FTP server. One very useful touch, especially for updating your personal web site is that you can save your changes directly to the remote file, sitting on the FTP server.
