body: <p>What is the fastest way to read individual files (in a random fashion) from a zip file? </p>
  
  <p>As I understand it, zip files have a directory that stores the individual file entries, and I could scan this directory to build an external index. Are there any standardized ways (i.e. existing libraries) that already do that? Or could I use a specialized type of zip file? </p>
