zsync is a file transfer program. It allows you to download a file from
a remote server, where you have a copy of an older version of the file on
your computer already. zsync downloads only the new parts of the file. It
uses the same algorithm as rsync. However, where rsync is designed for
synchronising data from one computer to another within an organisation,
zsync is designed for file distribution, with one file on a server to be
distributed to thousands of downloaders. zsync requires no special server
software — just a web server to host the files — and imposes no extra
load on the server, making it ideal for large scale file distribution.
