File Transfer Protocol (FTP) was the standard method of sending and retrieving files over the Internet without the need to use an email attachment or a browser to open the file. It has been replaced by the Secure File Transfer Protocol (SFTP) and the Secure Copy protocol (SCP) which encrypt your login and data, because old FTP operated insecurely (without encryption).
SFTP and SCP are particularly useful for transmitting or receiving large numbers of files (such as whole directory or a Web site) without having to click on each one individually.
This document explains how to use programs which run SFTP and/or SCP. It describes programs for the three most popular platforms: Microsoft Windows, Unix, and Apple Mac OS X. This document assumes you are completely familiar with using your computer and operating system, and that you know and understand files, folders (directories), Web sites, URIs, and usernames/passwords. If you are uncertain about any of these, please refer to the Training Centre pages for details of courses.

6. Trouble-shooting
In WS_FTP, error messages are displayed in the small window at the bottom: watch out for them!
If there is a network failure, or if there are already too many people using the remote machine, your connection will be terminated. All you can do in this case is try again later.
If you mistype the machine name or number, you will get a message saying that it is an ‘unknown host’. In this case, check the name or number with your systems administrator and try again.
If it still won't work with the name, then it usually means that the ‘nameserver’ (the machine your site uses to convert names to numbers) is unable to resolve the name: try the number instead if you can get it by some other method.
If a long transfer looks as if it has halted or got stuck, it's best to cancel it and try later.
