I think File[] files = folder.listFiles() can only list the first level of files. Is there a way to list files recursively?

Yes. Write a recursive method. – juergen d Apr 19 '12 at 15:24 — juergen d, Apr 19 '12 at 15:24

Not a built-in one, but you can write a short recursive program to do walk the directory tree recursively.

void listAll(File dir, List<File> res) {
    for (File f : dir.listFiles()) {
        if (f.isDirectory()) {
            listAll(f, res);
        } else {
            res.add(f);
        }
    }
}
