What Is a 7z File and How to Open it?

You’ve almost certainly come across archive formats like ZIP and RAR when downloading and sharing files. You may have also encountered 7z files — which are specific to the popular compression tool, 7-Zip.

Maybe you’ve downloaded one of these files from the internet, or perhaps a colleague has sent you one via email. Whatever the case, if you want to learn what it is and how to open it up and access the files within, you’re in the right place!

What Is a 7z File?

Similar to a ZIP file, a file with a .7z file extension is a compressed/archived file. The 7z format is newer than the ZIP file format and it provides a high level of compression. One benefit of using the 7z format is that it can be used with files that you want to split into several smaller parts. This is especially helpful when transferring or downloading larger files or folders.

Are 7z Files Safe?

They are no less safe than any other similar file formats. However, as with any file, you should only open 7z files from trusted sources because there is always the possibility that a 7z file could be malicious.

– Double-click it.
– Select Open With > Archive Utility.

That’s it! But quite often, especially when you have multiple files zipped into a single archive, you might want to browse the file’s contents and extract a few files without unzipping everything. While it’s not possible to do with Archive Utility, you can do so with Unarchiver One:
1. Download and launch Unarchiver One.
2. Drag and drop the 7z file into the app.
