title: a faster way of decompressing a large zip file
body: <p>I am writing a program that extracts images from zip file and catalogues them. </p>
  
  <p><code>System.IO.Compression.ZipFile.ExtractToDirectory</code> seems to work fine for smaller files but it is really really slow for <em>big files</em> (>4GB), is there a faster library out there? I don't need anything special just to extract the zip file into a directory.</p>
