title: Untar multipart tarball on Windows
body: <p>I have a series of files named <em>filename.part0.tar, filename.part1.tar, &hellip; filename.part8.tar.</em></p>
  
  <p>I guess tar can create multiple volumes when archiving, but I can't seem to find a way to unarchive them on Windows. I've tried to untar them using 7zip (GUI &amp; commandline), WinRAR, tar114 (which doesn't run on 64-bit Windows), WinZip, and <a href="http://www.zentastic.com/blog/zentar-win32-untar-utility/" rel="noreferrer">ZenTar</a> (a little utility I found).</p>
  
  <p>All programs run through the <em>part0</em> file, extracting 3 rar files, then quit reporting an error. None of the other part files are recognized as <em>.tar, .rar, .zip,</em> or <em>.gz.</em></p>
  
  <p>I've tried concatenating them using the DOS copy command, but that doesn't work, possibly because <em>part0</em> thru <em>part6</em> and <em>part8</em> are each 100Mb, while <em>part7</em> is 53Mb and therefore likely the last part. I've tried several different logical orders for the files in concatenation, but no joy.</p>
  
  <p>Other than installing Linux, finding a live distro, or tracking down the guy who left these files for me, how can I untar these files?</p>
