Htaccess Directory

I need to make all content under a certain directory with one exception. There is one directory that has to be accessible through the browser.

The layout could be something like this:

backend/

|-admin

|-system |-themes |-uploads

You can deny all access by placing an htaccess under backend file with the following:

Order Deny,Allow
Deny From All

You then need to overwrite this rules under uploads with a another htaccess file with this orders:

Allow From All
