title: Can I create a byte[] straight from a folder?
body: <p>A web Service expects a <code>byte[]</code> coming from a zip file.</p>
  
  <p>I have some files in a folder that I zip with Java and then I get the <code>byte[]</code> from this zip file.</p>
  
  <p>Is this necessary or can I create the <code>byte[]</code> straight from the folder?</p>
