Opening up back ups

Hiya so I’ve switched computers and I’ve backed up my projects and I’m currently trying to open these projects on my new computer. I open the projects and it has all my folders and documents but nothing inside of them. In the same back up folder I have words docs of all my work. There should be a way to have everything open together. I still have the old computer so I can make a new back up if I did that incorrectly.
