Which one is the root file of our project?

The root file of a project is typically the main file that serves as the starting point of your project. It's often named after the project itself or simply called "main" or "index". For example, in a Python project, it might be "main.py". In a web project, it might be "index.html". However, the specific name can vary depending on the programming language, framework, or personal preference.

Here are the steps to find the root file:

1. Open your project directory: The root file is usually located in the base directory of your project.

2. Look for a file named after your project, "main", or "index": These are common names for root files.

3. Check the file's content: The root file usually contains high-level logic and calls to functions defined in other files.

4. Look at your project's documentation or README: If you're still unsure which file is the root, the project's documentation or README file often specifies it.

Remember, the root file is crucial as it's the entry point to your project. It's where the execution of your project starts.
