Understand and open a file
Use a computer with a mouse and keyboard. This practice desktop is designed for clicking, right-clicking, dragging and typing with physical keys, rather than touchscreen use on a phone or tablet.
A file is something you have saved

You are going to open Packing list.txt and read what is inside.
You will learn what a file is and how an app shows its saved contents.
A file is a saved item, such as a photo, a letter or a list. A folder keeps files together. An app is a program that lets you view or work with them. Opening a file asks an app to show its contents.

Our file is called Packing list.txt. The .txt ending identifies it as a text file, and Documents is its saved location. This ending is called a file name extension. Windows may hide extensions; our example shows them.

See the saved words appear
Packing list.txt is ready in Documents. Follow the instruction popup and open the file yourself on the practice desktop to read its saved words. Afterwards, Try it gives you a fresh desktop to practise independently. Click Check my work when you finish, or use the optional hints underneath.
Click Documents on the left, then double-click Packing list.txt: click its name twice quickly. You can also click it once and press Enter on your keyboard. Its saved words appear in Notes. Click the X at the top right of Notes to close it and return to File Explorer. The file remains in Documents.

The same file, with the same saved words.
Try this outside the practice desktop
You have practised inside this webpage. If you feel ready, you can repeat the skill in Windows on the same computer, outside the practice desktop. This is optional. The steps below use your actual apps and files, so use only disposable practice items. Files made in the webpage do not appear in Windows File Explorer.
The file is the saved item. Its folder is where you keep it, and an app shows what is inside. Different types of file may open in different apps.
