How to make a page link to a file?

Hello,

How do I make a page link to a file instead of the page? For example. I have a page called “network marketing” and the link for that page is https://www.mywebsite.com/network-marketing/ by default. However, I want that page to link to https://www.mywebsite.com/network-marketing/resources.html.

Is this possible to do? Where do I need to change the code?

Thank you.
