The File Transfer Protocol (FTP) is the most popular protocol for obtaining files over the Internet. Thousands of FTP sites have been set up to allow the public to download and try out files. You can even set up your own FTP sites using a FTP server. While web browsers have become more popular for transferring files as a result of their integrated FTP capabilities, standalone clients retain more functionality and features than the internal FTP clients found in browsers. For the serious file-grabbing netizen, a standalone FTP client is the only feasible option.
