Error when I am making a search of a file in NetBeans

Question

private void SearchbtnActionPerformed(java.awt.event.ActionEvent evt) {
    String answer1 = TxtFi.getText();
    Scanner sc = new Scanner(answer1);
    name = sc.nextLine();
    try {
        getRootPath();
    }
    catch (IOException e) {
        e.printStackTrace();
    }
}

public static void getRootPath() throws IOException {
    File[] files = File.listRoots();
    for (File f : files) {
        System.out.println(f.getPath());
        parseAllFiles(f.getPath());
        if (count == 1) {

        }
        if (count > 1) {

        }
    }
}

public static void parseAllFiles(String parentDirectory) {
    File[] filesInDirectory = new File(parentDirectory).listFiles();
    File[] desktop = new File("C:\\PDF FILES").listFiles();
    try {
        if (filesInDirectory != null) {
            for (File f : filesInDirectory) {
                if (f.isDirectory() && !f.toString().startsWith(".")){
                    parseAllFiles(f.getAbsolutePath());
                }
                file = f;
                path = f.toString();
                if (file.getName().equalsIgnoreCase(name) || file.getName().toLowerCase().contains(name.toLowerCase())) {
                    count++;
                    fileX = file;
                    Desktop.getDesktop().open(fileX);
                }
            }
        }
    }
    catch (IOException e) {
        e.printStackTrace();
    }
}

public static void main(String args[]) {
    java.awt.EventQueue.invokeLater(new Runnable() {
        public void run() {
            new kainourgio2().setVisible(true);
        }

I tried this code and it worked. I am making a search of a file in my computer C:\. The file can be anything from pdf to doc. It opens from any doc viewer or pdf viewer that is on my computer. The problem here is that when I click the exit button the frame does not close or exit. I expect to do a lot of searching for files without the program crashing but now I can only do one search. I can't do anything else after the first search. It's like my program is stuck in an endless loop. I do not see any error messages in the console or NetBeans output window.
