Latest installation of WordPress (Version 4.1.1) has a file structure not much different from previous versions. This is what you will see after unpacking the zip file.

Three themes are included, with twentyfifteen being activated as default. I later added another theme, twentyfifteen-child, for experimentation, and then twentyeleven and twentytwelve for comparison purposes.

Two plugins are included.  Akismet does an excellent job of diverting spam, and hello.php is a simple demo plugin.

Several blank index.php files are used to prevent some servers from displaying the directory contents.
