In PowerShell v5.1 this is slightly different compared to v5. According to MS documentation, it has to have a <code>-Path</code> parameter to specify the archive file path. 

<pre><code>Expand-Archive -Path Draft.Zip -DestinationPath C:\Reference
</code></pre>

Or else, this can be an actual path:

<pre><code>Expand-Archive -Path c:\Download\Draft.Zip -DestinationPath C:\Reference
</code></pre>

MkDir("C:\a")
foreach ($item in $zip.items()) {

What's wrong? The directory <code>C:\a</code> is still empty.
