 public static void main(final String[] args) {

    JFileChooser cho = new JFileChooser();

    disableButton(cho, "FileChooser.homeFolderIcon");


    cho.showOpenDialog(null);

}

public static void disableButton(final Container c, final String iconString) {
    int len = c.getComponentCount();
    for (int i = 0; i < len; i++) {
        Component comp = c.getComponent(i);
        if (comp instanceof JButton) {
            JButton b = (JButton) comp;
            Icon icon = b.getIcon();
            if (icon != null
                    && icon == UIManager.getIcon(iconString)) {
                b.setEnabled(false);
            }
        } else if (comp instanceof Container) {
            disableButton((Container) comp, iconString);
        }
    }
}
