Map url to file

I have a theme which I bought that has templates for buddypress in a folder called members>single which overrides bp templates such as home.php, activity.php etc.

I’m trying to include one of my own templates in this folder but when I enter the url I get a 404. This is the url mydomainname/members/user1/likes/.

Can someone else tell me what else I need to do to get it to map to this file path.

Thanks
