Here is an instruction onto how you can check that:<br>1) extract first ~700M from the archive (takes 1-10 seconds)<br># 7z e enwiki-20100130-pages-meta-history.xml.7z<br># Ctrl-C<br><br>2) open the .xml file and search for 9450068<br>
You'll see that the revision text is missing.<br><br>3) Check that this revision is in fact not an empty one:<br><a href="http://en.wikipedia.org/w/index.php?oldid=9450068">http://en.wikipedia.org/w/index.php?oldid=9450068</a><br>
<br>4) Scroll down in the .xml file and see more empty and regular revisions.<br><br>-- Dmitry<br>
