Understanding Joomla! installation
A complete Joomla! installation includes a large number of directories and files. The directories and files reside on your server, typically, though not necessarily, in the public directory of your hosting account.
Table 2.1 shows is a view of the default installation of Joomla! 1.5.10, with all the key directories expanded to give you the big picture of what is installed on your server. See Appendix B for a map of the locations of the key files and directories that you might need to locate during the customization of your site.
