title: How can I recover files from a corrupted .tar.gz archive?
body: <p>I have a large number of files in a .tar.gz archive.  Checking the file type with the command</p>
  
  <pre><code>file SMS.tar.gz
  </code></pre>
  
  <p>gives the response</p>
  
  <pre><code>gzip compressed data - deflate method , max compression
  </code></pre>
  
  <p>When I try to extract the archive with gunzip, after a delay I receive the message</p>
  
  <pre><code>gunzip: SMS.tar.gz: unexpected end of file
  </code></pre>
  
  <p>Is there any way to recover even part of the archive?</p>
