To stop access to a directory (and anything in that directory) all you need is a simple RewriteRule.

RewriteEngine on
RewriteBase /
RewriteRule ^exampledirectory/(.*)$ / [R=301,L]

In this example, if this .htaccess file resides in the root directory of the site and you try to access anything within /exampledirectory you will be redirected back to the root folder. To redirect to another folder (like anotherdirectory) on your web server use the following rule.

RewriteEngine on
RewriteBase /
RewriteRule ^exampledirectory/(.*)$ /anotherdirectory [R=301,L]
