Q: I can't open the exercise files. What's this .7Z extension?

A: The .7Z extension is for a 7-Zip file. 7-Zip is an open-source file compression standard that is similar to a ZIP file, but it has a much better compression rate in certain situations. For the exercise files in this course, using a standard ZIP file would have added around 150MB to the download size, so we opted for a more efficient format.
To extract the .7Z file, you'll need some free software. If you visit, you can find free, open-source software for Windows. For Mac users, please see to download Keka, a free application that can do the same. For those with software security policies in place, Keka is also available on the Mac App Store for $1.99.
