public class Test {
    public static void main(String[] args) {
        File root = new File("c:\\test");
        String fileName = "a.txt";
        try {
            boolean recursive = true;

            Collection files = FileUtils.listFiles(root, null, recursive);

            for (Iterator iterator = files.iterator(); iterator.hasNext();) {
                File file = (File) iterator.next();
                if (file.getName().equals(fileName))
                    System.out.println(file.getAbsolutePath());
            }
