To transform your lovely_photos.7z file into a complete "paper" project—whether that means a physical scrapbook, a digital photo essay, or a printed album—you'll first need to access the images and then choose a format for your work. Step 1: Extract Your Photos

A .7z file is a compressed archive. You must extract the photos before you can use them.

You can download the official tool from the 7-Zip website or use a free tool like Unzip One from the Microsoft Store.
