How can I see the file structure like this?

I am using VS code.

Hi Doris, and welcome to the community!

If you are using VSCode, you can use the “Explorer” View on the left sidebar to see the file structure of directories and files.

Just click on the top icon (see image above) and you should see the structure appear in the sidebar. You can click on the little arrows next to the directory names to expand and collapse each directory. If you don’t see a sidebar, you can use command-b (mac) or control-b (windows) to get that sidebar to re-appear.

Let us know if you’re still having trouble.
