FTP is extremely useful for retrieving information from

Internet archives. Such Internet site contains a wide variety of information and most large software suppliers maintain their own archives containing upgrades to their software. A great deal of software is also available free of charge from archives, including large-scale applications and even full operating systems.

FTP is designed to be useful to any Internet user, irrespective of the Operating System or hardware used. In order to facilitate this, FTP offers different ways to transfer files dependent on their contents. Straightforward ASCII files are transferred in the most appropriate way for the user. Binary files (for example program files) are transferred in byte by byte fashion.

Using FTP requires that the user login to the computer that are to be copied. Login in this context means that the user has an account on that computer and has been given a user name and password. This is major limitation for Internet archive sites that must be able to service many million potential users. It is obviously impossible to set up accounts for all of this population. To get around this difficulty, it is usual to set up an FTP site to allow for Anonymous FTP. In this case users can access the archive without needing an account. They can login using the user name anonymous and either no password, or perhaps their e-mail address.
