Codewars is a website that lets you solve thousands of code challenges to improve your programming skills. You can create an account and see the code challenges (known as “kata”) that users have created (you can create one by yourself, too!). What this program does is pull all the data from the katas you've completed and create folders and files corresponding to them, so you can have a well-organised index of all of them in a folder. If you're interested, I recommend you head to the Codewars website and investigate how the website works and what you can do.
