Denying access to all files except index.html apache

Question

Could someone help me with apache .htaccess file to deny access to all files and sub directories except for index.html on the documentroot for an apache server?

I tried:

<Location />
    Order deny,allow
    <Files index.html>
        Order allow,deny
    </Files>
</Location>

but that didn't work.

Answer 1

Try this:

Order allow,deny
Deny from all
<FilesMatch index\.html>
        Allow from all
</FilesMatch>

Answer 2

On Apache 2.4.18, inside an .htaccess file, I found that neither <Files index.html> nor <FilesMatch index\.html> nor <Files ""> etc. reacted to directory-index request URLs ending in a slash; they applied only if the request URL actually ended in index.html. I eventually managed to grant access without authentication to all URLs ending in a /, but require authentication for all other files, with

Require expr "%{REQUEST_URI} -strmatch '*/'"
Require valid-user
