I have made two JScrollPane components. The left one shows the directories in USB and right shows the directories of a local drive. For I am able to display the complete file path as shown in first pic. But I want to display it with icons just like the way directories are displayed in any local drive on PC. This is my designed GUI, here is the example of what I want example
public class MainForm extends javax.swing.JFrame { iRecordCopy obj = new iRecordCopy();
public MainForm() {
initComponents();
}

Here a short example to create a minimal JList with file icons, it displays the content of the user's home directory using the system file icons.
