Where should .htaccess go?
 

I have my .htaccess in photopost root, which gives me SEO-ed URL's that look just fine.

From the Admin menu I can select "Edit data .htaccess" and "Edit fullsized .htaccess". When I click on either link the admin screen shows a blank edit area, above that it displays "File being edited: /home/username/domains/proeftuintje.nl/public_html/fotos/data/.htaccess"

So I am confused. Where should .htaccess go?

Why does the Admin menu try to load ./data/.htaccess?

Additional question: what do these lines do?

#RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} !-f
#RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} !-d

They are commented out. Should I remove the # 's?

(edit: I have searched the forums but did not find an answer)

The main htaccess for SEO goes in your gallery root

The data htaccess is merely a file to restrict gallery files etc
