Child Theme Question

Are *all* php files supposed to be picked up by the child theme?

For instance, if I want to make a change to ….


….and I copy that file to my child theme with the same directory structure


Then I make changes to the file that resides within the child theme.

Shouldn’t the change I made to that file in my child theme show up on my site? I’m doing this and not seeing the changes. If I make them in the parent theme they show up fine.

I’m really sorry if this is a dumb question but I’m confused about the reason why this isn’t getting picked up.

Thank you for any assistance that can be offered. I’m pulling my hair out here.
