Windows operating systems provide native support for ZIP files, but not for the 7z format. Thankfully, the free and open-source 7-Zip app is all you need to open and extract the contents inside 7z files. Start by downloading and installing 7-Zip from 7-Zip.org. The installer is completely free of adware, so don’t worry. Then, right-click any 7z file on your PC, and you’ll find a 7-Zip contextual menu option. If you use Windows 11, you must first select Show more options to reveal it. You’ll then come across a range of options. The most important is Open archive, Extract files, and Extract Here.

The program also features a Delete option that lets you remove items from the archive. Alternatively, you can launch the 7-Zip File Manager via the Start menu and select File > Open to load and view a 7z file from any directory on your PC.  Extract files: Extracts the contents of the entire 7z file. Specify a directory and select Extract. Extract Here: Lets you instantly extract the entire contents within the 7z archive into the same directory.

Alternatively, you can open Archive Utility via Spotlight Search and select File > Open Archive to select and extract the contents of any 7z file. If Archive Utility fails to extract a 7z file, your best option is to grab The Unarchiver from the Mac App Store. It’s a completely free utility that features full support for the 7z format. It also provides GUI-based options such as the ability to move archives to the Trash after extracting. If you prefer the ability to preview 7z files before extracting them, try BetterZip. It also allows you to create 7z archives on the Mac from scratch and comes with a 30-day trial. It costs $24.95 per license. You can open 7z files directly using the BetterZip app, or by control-clicking a file and selecting BetterZip > Open in BetterZip. You can then choose to extract or delete select items within the archive.

Open, Extract, and Compress in 7z

7z is a solid compression format. But it’s not popular, leads to confusion, and lacks support on various desktop and mobile platforms. Although you now know how to open, extract, and even create 7z files, it’s best to stick with the ZIP or RAR formats for any files or folders you plan to share … at least until the 7z format goes more mainstream.
