Creating, Editing, and Saving Files in VS Code

Creating a New File

Let's start by creating a new file in Visual Studio Code. This is where you'll write your code or text.

1. Open the Command Palette: Press Ctrl+N (Windows/Linux) or Cmd+N (macOS). Alternatively, you can go to the File menu and select New File.
2. A new, untitled file will open. You'll see a blank editor window ready for your content.

Writing Text into the File

Now that you have a new file open, you can start typing!

1. Type some text: For example, you could type "Hello, world!". This is a common first program in many languages.
2. VS Code automatically detects the language: Based on the content you type, VS Code will attempt to detect the programming language you're using and provide appropriate syntax highlighting.

Saving the File

Saving your work is crucial to avoid losing it.

1. Open the Save Dialog: Press Ctrl+S (Windows/Linux) or Cmd+S (macOS). Alternatively, go to the File menu and select Save.

2. Choose a File Name: A dialog box will appear asking you to enter a file name. Type in a descriptive name for your file. For example, my_first_file.

3. Choose a Location: Select the folder where you want to save the file. You can navigate through your computer's file system using the save dialog.

4. Select a File Extension: This is very important! The file extension tells your computer what type of file it is and which program should open it.

   • .txt: For plain text files.
   • .py: For Python files.
   • .html: For HTML files (web pages).
   • .js: For JavaScript files.
   • .css: For CSS files (styling for web pages).

   For this example, let's save the file as my_first_file.txt. Type the file name including the .txt extension in the "File name" field.

5. Click "Save": Your file is now saved! You'll see the file name appear in the VS Code title bar.

Why are file extensions important?

File extensions are how your operating system knows what kind of data is in the file. If you save a Python program as my_program.txt, your computer won't know to run it with the Python interpreter. It will likely open it as a plain text file. Choosing the correct extension ensures the file is handled correctly.
