title: .svn folder was in every folder but now it's gone
body: <p>I have used TortoiseSVN for a long time.
  And I started using AnkhSVN yesterday.
  and after that hidden ".svn" in every sub-folders are deleted.</p>
  
  <p>I googled it for some time, but I failed to find it.
  ".svn in every folder" is not necessary anymore?</p>
  
  <p>Thank you.</p>
