Uploading and Downloading from FTP Sites

Hooking into an FTP site generally requires an FTP client program that runs on the kind of computer you use (Mac, Windows, or whatever). On Mac OS X, popular FTP client programs include the shareware programs Fetch, Interarchy, and Captain FTP, and the free RBrowser Lite (available from http://www.versiontracker.com, for example).

Using these programs, Web designers, for example, can view a list of all the text and graphics documents, sitting there on an Internet-connected computer somewhere, that make up their Web pages. When they want to update one of those pages, they add it to this list; to delete a Web page, they remove it from this list.
