What The File


What The File adds an option to your toolbar showing what file and template parts are used to display the page you’re currently viewing.

You can click the file name to directly edit it through the theme editor, though I don’t recommend this for bigger changes.

What The File supports BuddyPress and Roots Theme based themes.

More information can be found here.
