Files and Containers

When you look at icons on your computers, you will see two types: Files and Containers.

Files are usually either Programs, or Documents.

  • Programs are tools. They do things. They make text documents, pictures, or sounds; they allow you to play games, look at the Internet, or do anything you can do on a computer. The icons usually look like little pictures of what the program does, or like a logo. Programs are sometimes called Applications or Software.
  • Documents are information. They are made by programs. They contain text, pictures, sounds, movies, or special information for any program. The icons look like a little piece of paper with one corner folded down.

Containers are either Volumes or Folders.

  • Volumes are physical containers of data, like a CD, DVD, Floppy, Hard Drive and so on. They usually look like a small picture of the Hard Drive, Floppy, CD, etc. They can contain files and folders.
  • Folders (also called "directories") are imaginary containers of data. They do not really exist. They are just a way to separate files from each other. If we had no folders, then all the files would be together in one place. Folders allow us to organize the files into separate areas. They can contain files and other folders, but they cannot contain volumes.
