When building your Joomla! template it's useful to know where in Joomla! the files for each template are stored within your website's hierarchy.
Open your FTP program if your Joomla! website is stored on a remote server and locate the root directory of your Joomla! installation. Let's assume that our Joomla! installation is on example.com
and that we're using FTP throughout the book. We'll use FileZilla, which can be downloaded for free from http://filezilla-project.org.
By storing related files such as CSS files, images, and the template files together in a Joomla! template, it's easier to see which files relate to a particular Joomla! template.
