    public File getFile(){
        final JFileChooser fc = new JFileChooser();
        fc.setFileSelectionMode(JFileChooser.FILES_AND_DIRECTORIES);
//        JFileChooser.FILES_ONLY
//        JFileChooser.DIRECTORIES_ONLY
        int returnVal = fc.showOpenDialog(this);
        File file_choosed = fc.getSelectedFile();
        return file_choosed;
    }
