i've a doubt about whai is included in the option "Include

Hi

i've a doubt about whai is included in the option
"Include common files: Themes, Plugins, Media (wp-content/uploads)" is really everything included in this option, or i have to select the next option "Include selected files:" and check everything.

because in "Include common files: Themes, Plugins, Media" looks like that wp-config.php and .htaccess are not included.

I really want a backup copy where everything is included
Thanks
