FielNotFoundException bei Datenbankverbindungsdatei

Guten Morgen Leute. Mit den Pfadangaben in Java habe ich noch so meine Probleme.

Im Bildanhand seht ihr meine Dateistruktur und hier zeige ich den Code wo ich eine Instanz auf das Datenbankverbindungsobjekt bilde.

Hier der Code wo ich das einbinde.
Java: 
import Connections.DbConnect;
import SystemGUI.MasterFrame;

public class Main {
	
	public static void main ( String [] args ) {
		DbConnect dbCon = new DbConnect( "../ConnectFiles/MySqlConnection.txt" );
		new MasterFrame( dbCon );
	}
}

Das Verbindungsobjekt wird dann im weiteren Programmverlauf an andere Mthoden und Klassen weiter gereicht.

Die gefeuerte Exception. ( ich denke das viele FEhler auf dem ersten aufbauen )

Kannst ja mal:
Java: 
File file = new File("file");
System.out.println(file.getAbsolutePath());
machen. Dann weisst du wo du bist...bzw eben nicht.


EDIT:
