Simply download and install QuickLook from the Microsoft Store, and you’re good to go. The next time you open up File Explorer, click on a file and hit Space to preview it. The app works with images, PDFs, videos, PSDs, and MP3s to quickly show you their contents; it can also show you what’s inside ZIP files.

In addition, QuickLook’s pop-up windows include a button to open up your selected file in the default app that’s best suited for that file type. It also lets you scroll through previews of every file in a folder with your arrow keys.
As someone who routinely works with all kinds of documents, photographs, and poorly labeled zip files from several email contacts a day, this app is a godsend.
