The settings.json file in VS Code is where you store custom settings that override the default editor preferences. If you're trying to find or edit it, here’s how to locate and work with it properly.

How to Access settings.json in VS Code

You don’t always need to manually find the file to edit it — VS Code provides a built-in way to open it directly.
To access it:

• Open the Command Palette (Ctrl Shift P or Cmd Shift P on Mac)
• Type "Preferences: Open Settings (JSON)"
• Click the result, and it will open the settings.json file in the editor

This method works whether you're editing user-level settings or workspace-specific ones. It avoids having to dig through folders manually.

Where Is It Stored by Default?

If you do want to locate it manually, the file is usually stored in a specific directory depending on your operating system:

• Windows: %APPDATA%\Code\User\settings.json
• macOS: $HOME/Library/Application Support/Code/User/settings.json
• Linux: $HOME/.config/Code/User/settings.json

These paths can vary slightly if you're using a portable version of VS Code or a different installation. Also, if you're working with a specific workspace, there may be a separate settings.json inside the .vscode folder of that project.

When to Use User vs Workspace Settings

There are two main types of settings.json files:

• User Settings: Apply globally across all projects
• Workspace Settings: Only apply to the current project and are often shared among team members

You can switch between them in the settings UI or by opening each JSON file directly. For example, if you want to set a special font size just for one project, put it in the workspace settings.json. But if you prefer a certain theme everywhere, use the user-level file.

It's also possible to have multiple profiles in newer versions of VS Code, each with its own settings.json, which adds more flexibility without cluttering the main file.

Common Mistakes to Avoid

Editing settings.json gives you a lot of control, but it's easy to make small errors that break things:

• Syntax errors like missing commas or incorrect brackets can stop settings from loading entirely
• Overwriting settings without realizing it — especially when sharing workspace files
• Assuming changes take effect immediately — sometimes you need to reload or restart VS Code

A good practice is to test changes incrementally and keep a backup of the original file, especially when troubleshooting issues like extensions not behaving as expected.

基本上就這些。
