title: Why does symchk download .exe and .dll files alongside with .pdb
body: <p>I'm building a local symbol cache of all binaries under my <code>c:/windows</code> using <code>symchk /r c:/windows</code></p>
  <p>Inspecting the contents of my symbol directory during and after running this command, I find many folders ending with <code>.exe</code> and <code>.dll</code> which contain actual binaries (in fact, duplicates of those under <code>c:/windows</code>) in addition to <code>.pdb</code> symbol files proper.</p>
  <p>I'd rather avoid wasting disk space with duplicates of files that are already present on my system. Is there any rationale for <code>symchk</code> behaving this way, and any options to download <code>.pdb</code>s only?</p>
