Where your files live

This is the first lesson in the free "Getting Ready for AI" path. Before you can use AI tools well, you need to be comfortable with the everyday stuff: where your files live, how to find them, and how to save them where you meant to. That is what this lesson builds.

Nothing here is hard. By the end you will be able to make a folder, save a file into it on purpose, and walk back through your folders to find it again.

Exercise · audit

Open your file window (File Explorer or Finder). Go into your Documents folder and make a new folder called "AI Course." Open any program where you can type, write one sentence, and use Save As to save it into that new folder with the name `my-first-file`. Then close it, walk back through your folders, and reopen it. If you found it again, you have done every outcome in this lesson.

Deliverable

Complete the hands-on task on your own device and note what you did, so the skill sticks.

Common misconceptions

  • “Hitting "Save" without checking where it is going”

    The computer often picks a folder for you, and it may not be the one you wanted. Always glance at the folder name before clicking Save.

  • “Leaving the name as `Untitled` or `Document1`”

    A vague name today is a lost file next week. Name it for what it is.

  • “Trying to change a file's type by retyping its extension”

    Renaming `photo.jpg` to `photo.pdf` does not turn it into a PDF. It just confuses the computer. Use the program's "Save As" or "Export" to change a file's type.
