A look at the Folder Hierarchy of the Mac

In this lesson for macOS Mojave on the Mac, I look at the folder hierarchy of macOS Mojave. The better you understand how your Mac is organized, the easier it will be to keep it organized with your files and folders.

Folder Structure
macOS is installed the Macintosh HD by default. This is the hard drive that is on your computer. Think of this hard drive as a filing cabinet. When you open Macintosh HD, you’ll see 4 folders, think of these for folders as drawers in your filing cabinet. These four folders are:

  • Applications: This is where all your applications are stored. If you install a new application, it will be installed in this folder. Nothing else should be stored in this folder.
  • Library and System: These next two folders are used by macOS and should not be touched.
  • Users: This last folder contains all the user files and folders including your documents and downloads. Your computer can have multiple users, so when you open the Users folder, you will see all your users. In most cases, it will just be a single user. When you open the users’ folder, you will see the documents, downloads, music, movies, and other folders. This is where all the users’ files and folders are stored.
