New description value

I want to insert new description value into the member info block which you get when you are searching for a site member for example. (I attached a screenshot incase I named it wrong). It only shows nickname and headline, how do I add new values there: for example to show one of pre-defined values like age,sex, or the custom one I created?

What changes should I make, what to add and in which files?

Thank you

Maybe someone can tell me what files generate this block?

You can only choose what to show there, to do it go to admin panel > settings > advanced settings > profiles > Member Brief Info

Believe that AntonLV has a module that helps in achieving this. Search the market. Possibly use "Profile" as keyword.

 Yes, but still the choice is still limited there. I just want to figure out which files contain theese settings? I edited group info before to show category instead of location, and it worked well that is why I believe change for brief info is possible if to work inside php/html files. And as you already understood I cannot figure out which ones :)

 Thank you, I will check his products to see if something can work for me:)
