Automatically create folder in Csharp project with audio files

Question

I have a project in C#, created a folder in the project by Visual Studio 2019 and put 2 Ogg’s there. The structure is as follows:

• App
  • Assets
  • Files (this is the folder I put the audio files in)
  • Model
  • View
  • Viewmodel

I have a question, every time I compile to test the application (CTRL + F5) it does not create any folder in the bin/Debug project, ie, the folder I created in the project is not being replicated when I compile the Debug.

I know I can create the folder in the application with the command below:

    var path = Application.StartupPath + @"\Files\";
    if (!Directory.Exists(path))
    {
          //Se não existir cria a pasta na raiz do projeto
          Directory.CreateDirectory(path);
    }

The problem is that the audios do not go to the folder and they are fixed audios, do not change, I already want the application to play those audios when the application opens.

Someone can help me?
