You should now have a final, clean version of the site, with a copy of the database, all zipped up and ready to go. Assuming there are images and a fair bit of data held within the site, you can be sure that the size of the upload is quite substantial. For this reason, you need a reasonably high speed connection—dial-up connections can be slightly erratic over long periods of time, so it may even be worth using a friend's computer (or your office connection) to send the files to the host site via a broadband connection.

By far, the easiest method would be to use a native upload feature from the host's file manager over a quick connection. If this is available, simply use it to upload the archive file across to the host server. The demo site has this facility, as shown here:

Notice that the ZIP file is being uploaded to the public_html folder, because this is the document root from which all web pages on this server are served.

Alternatively, assuming your site has an FTP account enabled, either attempt to use FTP drag-and-drop, which is exactly the same as moving files around on your PC in Windows, or make use of an FTP utility.

When in doubt, simply get in touch with your host service and ask them for information about how to transfer files. The administrative interface and file manager for the vast majority of sites are easy to use, and you will have no problems uploading files. Because of this, we won't waste time discussing FTP utilities in detail. Simply ensure that, ultimately, the ZIP or gzip file ends up in the document root of your host's server.
