How to get a page de-indexed?

In the pages for my site that Google has indexed, it has my old cms (/cms/) which I don't want there anymore.

Anyone know how to get rid of it?

 

301 the pages to the homepage.

 

But the directory doesn't exist any more, and I don't really want to add it. Isn't there another way?

 

You can create a rule in your htaccess file, thats the best way. You can also use the google console.

 

Oh cool, thanks ^^;
