how to remove file extension in the URL? like for example site.com/link.php how to make it appear like site.com/link. I heard about .htacess but i don't know how..

In your .htaccess file:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ $1.php [L,QSA]

"$1.php" assuming you are using .php

If your pages are .html, you would use "$1.html" and so on.

Or create a directory called link and have an index.html inside it?

Maybe im miss understanding the question?

He wants that the link.html would be treated as directory so that is the only way to play with .htaccess
