body: <p>I have a problem.</p>
  
  <p>I have </p>
  
  <pre><code>foo -- ab
      |  |--bx -- bc
      |  |      |_xr    
      |  |--xb
      |
      |--bb -- bc
      |      |- bx -- bc
      |      |- xr   
  </code></pre>
  
  <p>I create file <strong>zip_files.bat</strong> inside directory <strong>foo</strong>:</p>
  
  <pre><code>IF EXIST ab.zip del /F ab.zip
  IF EXIST bb.zip del /F bb.zip
  jar -cMf ab.zip ab
  jar -cMf bb.zip bb
  </code></pre>
  
  <p>current, I can zip file to <strong>ab.zip</strong>, then unzip <strong>ab.zip</strong>, it like this (it doesn't like original folder structure):</p>
  
  <pre><code>ab -- ab -- bc
         |_bx -- bc
         |     |_xr    
         |_xb
  </code></pre>
  
  <p><strong><em>I want</em></strong> have file <strong>ab.zip</strong>, when unzip file <strong>ab.zip</strong> have:</p>
  
  <pre><code>bx -- bc
      |_xr    
  xb
  </code></pre>
  
  <p>I also want have file <strong>bb.zip</strong>.</p>
