    <div id="working-copy">
  
      <h4>Description</h4>
  
      <p>This metric inspects your repository's working copy using
        <a href="http://www.kernel.org/pub/software/scm/git/docs/git-ls-files.html">git ls-files</a> to identify the
        <em>n</em> (default 10) largest objects - and consequently the <strong>largest files</strong>.</p>
  
      <p>In some cases the same object hash will be displayed for multiple paths. <strong>This is not a bug.</strong>
        The way git stores <a href="http://git-scm.com/book/en/Git-Internals-Git-Objects">blob objects</a> - i.e. bytes on
        the filesystem that could be anything (e.g. a text file, source code, an image) - means that if you have
        <em>exactly</em> the same file in multiple places in your repository - perhaps a static test file - then the
        report will correctly output <em>all the paths on the filesystem where the object is referenced</em>.</p>

      <h4>Description</h4>
  
      <p>This metric thoroughly inspects your repository's history and identifies the largest files over a configurable
        threshold (defaults at 0.5 MB) that have been committed in the past <strong>but are no longer part of the working
        copy</strong>.</p>
