Set BBpress to Full Width in Pre-Build Theme Easily

I had never get a easy answer for this, now I did many try and got success.

Firstly and hopefully, you theme supports full width, copy the file template (for example, I had “template-full-width.php” in my theme folder) for full width and rename it to bbpress.php and keep it in the same folder which is your theme folder.
Secondly, get the bbpress tweak plugin and installed, select the bbpress.php file in options, and done!

A lot of people never get a good answer, now it is. Hope you like.
