    public static void main(String... args) {
        try {
            String sourceFileName = "D:\\Data\\sample.txt";
            String destinationFileName = "D:\\Data\\sample-copied.txt";

            File sourceFile = new File(sourceFileName);
            Path sourcePath = sourceFile.toPath();
            InputStream sourceStream = Files.newInputStream(sourcePath);
            try (OutputStream outputStream = new FileOutputStream(destinationFileName)) {
                IOUtils.copy(sourceStream, outputStream);
