title: error -103 with zipfile in unzGetCurrentFileInfo
body: <p>I am reading the names of the files inside a zip archive through R with</p>
  <pre><code>unzip(myzip, list=TRUE)$Name
  </code></pre>
  <p>But I get an error:</p>
  <blockquote>
  <p>Error in unzip(myzip, list = TRUE) :<br />
  error -103 with zipfile in unzGetCurrentFileInfo</p>
  </blockquote>
  <p>Any idea what might be going on?</p>
  <h2>Extra info</h2>
  <ul>
  <li><p>Sorry I am unable to provide a reproducible example at the moment. I tried zipping again the first few files of the zip and it works correctly.</p>
  </li>
  <li><p>The zip is ~ 8Gb, 100+ Gb if unzipped.</p>
  </li>
  <li><p>It does not seem to be OS-specific. I get the same error on Mac and Windows. It is also not dependent on where the zip was created, I tried creating a zip of the first few files from a Mac or a Windows, and both run correctly.</p>
  </li>
  <li><p>I have two zip like this (zipped on different computers) and both throw an error, so it does not seem to be a random data corruption or something like this.</p>
  </li>
  <li><p>If I am reading correctly <code>?unzip</code>, it does not sound related to the size of my zip archive (8+ Gb). My zip contains ~ 3,000 files of ~ 30 Mb each, while unzip seems to have a problem with single files &gt; 4 Gb pre-compression. From <code>?unzip</code>:</p>
  </li>
  </ul>
  <blockquote>
  <p>[does not support..] &gt;= 4GB files pre-compression contained in a zip file: like many builds of unzip it may truncate these, in R's case with a warning if possible</p>

  <p>Any clues?</p>
