Arquivo properties não encontrado

Ola. Creio já ter tentado de tudo.

Segui por ultimo o link https://www.devmedia.com.br/utilizando-arquivos-de-propriedades-no-java/25546.

Continuo com o erro:

A classe de leitura é

public class Configuracao {

public static Properties getProp(int dbChoice) throws IOException {

Properties props = new Properties();
FileInputStream file = null;

switch(dbChoice){
case 0://ACCESS
file = new FileInputStream("access.properties");
break;
case 1://DB2
file = new FileInputStream("db2.properties");
break;
case 2://MYSQL
file =new FileInputStream("./properties/mySql.properties");
break;
case 3://ORACLE
file = new FileInputStream("oracle.properties");
break;
case 4://POSTGRES
file = new FileInputStream("postgres.properties");
break;
case 5://SQLSERVER
file = new FileInputStream("sqlServer.properties");
break;
}

props.load(file);
return props;

}
}

Obrigado pela ajuda
