        File file = new File("C:\\testing.txt");
 
        byte[] bFile = new byte[(int) file.length()];
 
        try {
            //convert file into array of bytes
     fileInputStream = new FileInputStream(file);
     fileInputStream.read(bFile);
     fileInputStream.close();
 
     //convert array of bytes into file
     FileOutputStream fileOuputStream =
