Change how the product list looks like

Hi everyone, i’m trying to modify how the product list looks like but i want to know how can i do this without modify the original file.

1 - Can i create a new file with the same name in somewhere else and changes it without change the original file?

2 - Is it possible to do the same with the address_html file?

@geekroot You can only change it via the CSS. Just create new templates if you want a new structure, or suggest fixes to the existing ones.

Ok thanks. i want to create a new template but i think when i need to update erpnext my changes will be lost.
