title: .svn folder is not getting created whenever i do a checkout
body: <p>i tried the following</p>
  
  <ol>
  <li><code>svnadmin create svn_repos</code></li>
  <li><code>svn import my_first_proj file:///c:/svn_repos -m "initial import"</code></li>
  <li><code>svn checkout file:///c:/svn_repos</code></li>
  </ol>
  
  <p>and the command returned</p>
  
  <pre><code>A    svn_repos\trunk
  A    svn_repos\trunk\Sample.txt.txt
  A    svn_repos\branches
  A    svn_repos\branches\my_pers_branch
  Checked out revision 1.
  </code></pre>
  
  <p>Yet the <code>.svn</code> folder was not created in the checked out folders.
  Because of which [I guess], I'm not able to do <code>svn  copy</code> or <code>svn merge</code>.</p>
  
  <p>Why does this occur?
  what is the problem?
  is there anything wrong in my commands</p>
