Definition: The `/wp-content/` prefix in the URL notation refers to a directory on the server's web server's home directory, specifically the content directory (in this case /wp-content). It points directly to the directory that stores all WordPress files and directories. The `/content.php` extension is used by WordPress as an alternative name for its PHP-based CMS. The `wp-content/` prefix means "the content directory of the server", not to be confused with the `wp-content` folder on your local computer's home directory (usually in `/home/user/documents`). In summary: - `/wp-content/` is a Unix-style path where "/wp" refers to the WordPress installation directory and ".content.php" points directly to all content files and directories. - The `/content.php` extension is used by WordPress for better readability.
