title: How to pack/unpack(read) idx files?
body: <p>Note: Using java.
  I've been searching almost all day on a way to pack an idx file. I only found something on another website &amp; they told me to rip it from something called an RSPS?... </p>
  
  <p>I just want to pack text files, models, images &amp; if possible a directory containing java files.</p>
  
  <p>I'm trying to build a packed/smaller cache for my game &amp; this is the most i've ever been stuck.</p>
