.htaccess rewrite - filename.html a /? c = filename

SPANISH: Hello, I need it to work with all the html links (except with index), I tried using .htaccess but I had no luck.

For example ... to change this link of: link to link

Also if I go directly to link , it should be a mirror of link

Thank you very much!
