copying files into child theme

So my question is, is it ok if I just copy all the theme php files into my child theme folder?

Copy only those files that you really need to edit/modify. Do not copy functions.php, but add only some non-conflicting additional functions in a skeletal file that may contain only something like this:

<?php

// add any additional functions here

I am sorry, I din’t understand your second sentence. Can you be more specific?

Thanks.

Re-read it. You don’t need to change all the functions, do you? So, just create a file with only what I have given above and then add your modified/ additional functions.

Let me make myself clear, I am not a programmer! I do know the meaning of half the things you said. What are functions? What are all those symbols
‘<?php

// add any additional functions here”

How do I create a file with what you have given above. That sentence doesn’t even make sense. Please help if you can make me understand, you are just confusing me.

Sorry if I am not clear to you. Please wait till someone else explains to you in a better way.

Please let me know if anyone else can help me.

For any .php files EXCEPT functions.php, you put a copy of the file in the child theme and make changes to the copy there.

For the functions.php file, do NOT copy it – it’s handled differently – see:

The specifics depend on what functions you are adding or changing.

OK now I got it, thank you!!
