title: Unzip all zip files in all subfolders
body: <p>Using a cmd batch file how can I iterate all the folders in a directory and unzip all the zip files in each folder? I have been able to get as far as iterating through all the subfolders but I can't iterate within each subfolder.</p>
  
  <pre><code>FOR /D %%R IN ("*") DO FOR /D %%S IN (*/%RR) unzip %%S
  </code></pre>
  
  <p>The folder structure</p>
  
  <pre><code>folder\subfolder1\zip1
  folder\subfolder2\zip2
  folder\subfolder3\zip3
  folder\subfolder4\zip4
  </code></pre>
  
  <p>I would like to have the contents of each zipfile extracted within it containting folder. The zip files and the subfolders have different names.</p>
