how to find a process's open files, i.e. what files does each process have open?

You can check how many instances of a particular program are running and what files are open by parsing the Process.MainWindowTitle property. For example, in the case of Notepad:

         Process[] procs = Process.GetProcessesByName("notepad");
         string fileName = "";
         foreach(Process proc in procs)
         {
            fileName = proc.MainWindowTitle.Trim().Replace(" - Notepad", "");
            Console.WriteLine(fileName);

}

It's possible to get a list of all running processes on the local machine using the Process.GetProcesses() method.

Having obtained the Process object, you can close it gracefully by calling its CloseMainWindow() method if it has a user interface or close it abruptly by calling its Kill() method if it has no UI. Needless to say, the latter can be dangerous and should only be used where you know it's safe to terminate the process in this way.
