An address for each creation

Three files are called “final”. Which one is the right map? Lumi decides to organize the expedition before the folder becomes a maze.

Let's discover together

  1. 1

    A folder groups items. Inside expedicao, a mapas folder can hold mapa-v1.txt and mapa-v2.txt. The path expedicao/mapas/mapa-v2.txt describes where to look; Windows also uses paths with backslashes.

  2. 2

    Use names that explain the subject and version. In this project, short lowercase names with hyphens help share examples across systems. This is a project convention, not a universal rule for every file.

  3. 3

    The extension is the ending, such as .txt or .png, that usually indicates the expected format. Renaming photo.png to photo.txt does not turn the image into text. The name alone does not guarantee a file is safe either.

  4. 4

    For optional practice, create only a new exercise folder in your documents. Do not reorganize system folders or other people’s files. On a phone, the manager may be called Files; menu names vary.

YOUR MISSION

Read a file path, choose useful names and distinguish renaming from converting.

Now it's your turn

Discovery workshop

Find the right version

The mission asks for the second text version inside mapas.
Build your answers and check when you are ready.
A moment to understand

Why does changing .png to .txt not convert an image?

I need a hint

The content is not rewritten when you only change the name.

Loading your journey…

Take it with you

Draw a folder tree for three imaginary files. Ask someone to find the second version using only the path you wrote.

Every lesson can become your own record: code, notes or a practice plan. Saving a file to GitHub is optional and does not change your XP.
