I have a duplicate URL from example.html to example without .html

[aptustelecom]

I've recently changed my links from example.html to just example, however, moz shows that its been duplicated. Is this effects my ranking? if yes, how i can fix it please?

No Shailendra is saying you want a 301 rewrite mechanism so that anyone looking for example.html is redirected to example.

If you have been using example.html for some time what happens to the guys who have linked to these pages, or any links you have created - they need to be handled by a 301 rewrite.  The snippet of code below placed in your .htaccess should fix.  Take a backup copy first to restore if you hit any problems.

in this case i have to change my links to example.html and the redirect them?

[aptustelecom]

no i didn't

the only thing i did, is just changed the [example](example.html>example</a> to <a href=)

If you want to get rid of the html files you could try the following in your htaccess file.  The rule looks for anything (.*), until it gets to the .html then rewrites the first part dropping the .html

RewriteEngine On
RewriteRule ^(.*)+.html$ $1 [R=301,L]

examlpe.html and example with the same content will be treated as duplicate pages. The best practice is to 301 redirect example.html to example.
