Opening a file in an application that is already running

I have it set so if you open a file, it launches my application and adds it to the start-up arguments. But how can I make it so if I double click on a file it loads it in the application that's already running? Rather than loading each file into it's own instance of the application.

Mutex is want you need to have a single instance of the application.

bool createdNew = true;
using (Mutex mutex = new Mutex(true, "MyApplicationName", out createdNew))
{
if (createdNew)
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new MainForm());
}
}

You can refer this LINK for detailed information.
