title: Archiving thousands of files and 7zip limitations
body: <p>My application requires that a task is run everyday in which 100,000+ PDF (~ 50kb each) files need to be zipped. Currently, I'm using 7-zip and calling <code>7za.exe</code> (the command line tool with 7-zip) to zip each file (files are located in many different folders).</p>
  
  <p>What are the limitations in this approach and how can they be solved? Is there a file size or file count limit for a <code>7zip</code> archive?</p>
