title: Is there a size limit to a blob for Utilities.unzip(blob) in Google Apps Script?
body: <p>I have a google script which accesses a website, finds a .zip file, unzips it, and extracts the relevant data from the relevant files. </p>
  
  <p>I want to do the same thing, but for a different, larger .zip file on the same site.</p>
  
  <p>I've accessed the .zip (using almost identical code), but it throws an error: "Could not unzip."</p>
  
  <p>My code:</p>
  
  <pre><code>  var dir = UrlFetchApp.fetch(url);
    var b = dir.getBlob();
    var files = Utilities.unzip(b);
  </code></pre>
  
  <p>The only difference between the two files are these:</p>
  
  <ul>
  <li>File A ends with "Update%201.8.5.zip" and contains 9 files (5.46MB, 5.15MB zipped)</li>
  <li>File B ends with "260_185.zip" and contains 407 files (384MB, 280MB zipped)</li>
  </ul>
  
  <p>This makes me think that there is a limit (size or number of files) to the Utilities.unzip() method. Can anyone confirm this, or is there something with the format of the filenames that is messing things up?</p>
