title: How to gunzip sql file in Windows?
body: <p>I have a .sql file created in Linux using:</p>
  
  <pre><code>mysqldump --opt db_name | gzip &gt; backup_file_name.sql
  </code></pre>
  
  <p>I need to use it in Windows. 7-zip can open it, but when extracting, it says "Data Error in backup_file_name.sql. File is Broken." I also tried <a href="http://www.gzip.org/#exe" rel="nofollow">http://www.gzip.org/#exe</a> and I can't get it to work. Any ideas?</p>
