A filesystem organizes a computer's files and directories into a tree structure:

  1. The first directory in the filesystem is the root directory. It is the parent of all other directories and files in the filesystem.
  2. Each parent directory can contain more child directories and files. Here blog/ is the parent of 2014/, 2015/, and hardware.txt.
  3. Each directory can contain more files and child directories. The parent-child relationship continues as long as directories and files are nested.

You're probably already familiar with this tree structure - Mac Finder and Windows Explorer represent the filesystem as trees as well.

At any point, you can reference the filesystem for this lesson here.
