title: How to find uncompressed size of ionic zip file
body: <p>I have a zip file compressed using <a href="http://dotnetzip.codeplex.com/" rel="nofollow">Ionic zip</a>. Before extracting I need to verify the available disk space. But how do I find the uncompressed size before hand? Is there any header information in the zip file (by ionic) so that I can read it?</p>
