title: unzip file using 7z in powershell
body: <p>What is the command to unzip a file using 7z in powershell?</p>
  
  <pre><code>set-alias sz "$env:ProgramFiles\7-Zip\7z.exe"
  sz x  $zipfilePath $destinationUnzipPath -aoa -r;
  </code></pre>
  
  <p>The command works fine but it says <strong>no files to process, everything is Ok</strong> rather than unzipping the file?</p>
