title: Symfony Finder ignores files beginning by dot
body: <p>I am using the Finder for sending spooled e-mails, but automatic name generator puts dots in the filename and sometimes they appear at the beginning of the file.</p>
  
  <p>It seems that the finder can't get files with that name - well those files are hidden... Has anyone experienced that behaviour? Any advice how to use the finder to locate hidden files?</p>
  
  <p>Thx</p>
