title: Moodle and SCORM .zip packages
body: <p>I have a scorm package that works in Moodle.  However, if unzip it to a folder and then rezip it and try to use it I get the following in Moodle:
  "Incorrect file package - missing imsmanifest.xml or AICC structure"</p>
  
  <p>Note, I'm doing this because I was trying to debug it and drilled down to this simple test:</p>
  
  <ol>
  <li>Start with working scorm .zip package "TestCourse.zip"</li>
  <li>On mac os x, I double click to extract it to the current folder.</li>
  <li>I cmd click on it and selected decompress which makes "TestCourse2.zip"</li>
  <li>I try to use "TestCourse2.zip" on Moodle as a scorm package and get the error above.</li>
  </ol>
  
  <p>I tried using a different program to re-zip the folder and got the same results.
  What am I missing here?</p>
