Pointing your home site's URL to a subdirectory In some cases, you may have a WordPress site that changes significantly every year, such as with a conference website. If you want to install each year's version of the site in a subdirectory, such as /2010, /2011, and /2012, but have the root domain (yoursite.com) automatically redirect to a particular subdirectory (usually the latest), follow this technique:
Install WordPress in a subdirectory, such as /2012. In your root folder (not the subdirectory folder), download and open your .htaccess file.
Add the following to your .htaccess file:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^(www.)?YourDomain.com$
