Where a File Lives: Folders, Names and Backups

Files sit inside folders inside other folders, and the path is the address that says which one. A name that describes the work, a place that makes sense and a second copy elsewhere are what make work findable later.

What a learner can do afterwards

  • Read a path and say which folder a file is in and what that folder is inside
  • Move a file and copy a file, and say what is different about the result
  • Say what the extension tells the machine, and what having only one copy risks

1 · Read

Every file lives at an address called a path. The path lists each folder you pass. Folders sit inside folders, like boxes in boxes. Read the path to find your work.

Try it together

Copying makes a twin. The first file stays put. A new twin lands in the new place. Moving takes it away. After a move it lives in one place only.

The tail of a name is the extension. A .jpg file is a picture. A .bat file lists jobs to run. The tail tells the machine which app should open it.

Good to know

Name your work for what it is. Keep it in a folder that fits. Hold a second copy in another place. Two copies in two places beats one.

Read the path, name things well, and keep a second copy elsewhere.
