Este artigo mostra como listar arquivos da pasta raiz em Java ME. A API FileConnection(JSR-75) e seu método FileSystemRegistry.listRoots() existem para este fim.

O código para teste do MIDlet:

Código fonte:

import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
import java.util.Enumeration;
public class RootMIDlet extends MIDlet implements CommandListener {
private Form form;
private Command exitCommand;
public void startApp() {
form = new Form("Root list");
exitCommand = new Command("Exit", Command.EXIT, 1);
public void pauseApp() {
public void destroyApp(boolean unconditional) {
protected void createRootList() {
Enumeration drives = FileSystemRegistry.listRoots();
while (drives.hasMoreElements()) {
String driveString = drives.nextElement().toString();
form.append(driveString + "\n");
public void commandAction(Command c, Displayable d) {
if (c == exitCommand) this.notifyDestroyed();
