Web DAV is another way to manage the files on your website, it's similar to FTP. Depending on what your operating system your computer uses or what kind of client program you use, Web DAV access might even look a lot like FTP.
On the Macintosh and Windows, a website accessed with Web DAV will look like another network drive. On the Macintosh this drive appears on the desktop, on Windows it's listed in the Network Neighborhood.
When you first signed up for an account, you should have received an e-mail that lists the Web DAV URL for your website. If you cannot locate this message or have forgotten e-mail Miles and he'll send that information out straight away.
