Problems redirect domain without www to www.domain.com

[wakeup]

In my hosting I have a .htacces in www root for redirect all pages from domain.com/page.html to www.domain.com/page.html

[code]RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !^www\.hhdirecto\.net [NC]
RewriteRule ^(.*) http://www.hhdirecto.net/$1 [L,R=301][/code]

It run ok, in folders too. But in subfolders with another .htaccess file it don't run.
I have tried to copy the same in the .htaccess in folder but it not run.
How can I solve it?
Thankss
