re: where I can find file for base information

Oh boy, I feel like a total idiot and using too much time of your support guys.....searching for hours to change some display of property size. It is about General Property info and land size. Love love display on listing yet I need to change the display on the property details page. Where I can find layout please help Mr Dam. What I try to achieve is to change the fact it displays let say 500.00 where I would love to display 500 m² see image below.

Guys I hope it is the last time I bother you here... and hope that you can lead me to the right file.
