Understanding the filesystem
When we say filesystem, we're talking about something you're already familiar with – how files and folders are created, organized, and stored on your computer. When you create a new folder on your computer, you can name it and put files or other folders inside it. It's also represented by an icon, which is both a visual cue and a way to drag, drop, and move it anywhere you like.
Everything you can do on your desktop you can do in code. All you need is the name of the folder, or directory as it's called, and a location to store it. Anytime you want to add a file or subfolder, you reference the parent directory and add your new content.
