String saveFolder = "C:\\";
Preferences pref = Preferences.userRoot().node(
this.getClass().getName());
String lastPath = pref.get("lastPath", "");
JFileChooser fc = null;
if (!lastPath.equals("")) {
    fc = new JFileChooser(lastPath);
} else{
    fc = new JFileChooser(saveFolder);
}
saveFolder = fc.getSelectedFile().getPath();
pref.put("lastPath",saveFolder);
