    If you use only standard tools, then in a simplified form like this:

    FileInputStream fis = new FileInputStream(new File("/path/to/file")); FileOutputStream fos = new FileOutputStram(new File("/path/to/destination/file")); byte[] buffer = new byte[512]; int rc; while((rc = fis.read(buffer)) != -1) { fos.write(buffer, 0, rc); } fos.close(); fis.close();
