.htaccess files (or "distributed configuration files") provide a way to make configuration changes on your Wordpress site on a per-directory basis. A .htaccess file, containing one or more configuration directives, is placed in a particular document directory on your Wordpress site, and the directives apply to that directory, and all subdirectories thereof. Using directives in .htaccess, you can block spam, secure your website, and control other website actions.
