Theme parts path location dump

Question

Few months back I was working on customizing theme that I was assigned to. I remember that I used some function or define something in the config or theme functions file and than it displayed debug information of exact path to every included file/partial, but I cannot remember what it was. I am googling for hours with no luck and I am running out of time (deadline).

When I set it it displayed path or url/uri to included files in currently opened file. Something like this but it also normally rendered the page. There was just this lines of debug information in it.

THEMEROOT/header.php
THEMEROOT/footer.php
and other partials

Now I have to customize very complex theme based on some kind of framework with hundreds of files and I am completely lost in it. I cannot find the location I need to change to achieve what I have to achieve.

I want to somehow dump this theme includes path but cannot remember how to do it and I running out of time. I've been googling for hours but did not find anything and it feels like a waste of valuable time.

Could someone point me at right direction?

While there are some WP–specific solutions that track template files, for complicated projects pretty much the only reliable list is using get_included_files() PHP function at the end of page load.

It would give you everything, including WP core, but filtering it down to theme is relatively easy.
