title: AzCopy Sync command is failing
body: <p>I'm issuing this command:</p>
  <pre><code>azcopy sync &quot;D:\Releases\Test\MyApp&quot; &quot;http://server3:10000/devstoreaccount1/myapp?sv=2019-02-02&amp;st=2020-06-24T03%3A19%3A44Z&amp;se=2020-06-25T03%3A19%3A44Z&amp;sr=c&amp;sp=racwdl&amp;sig=REDACTED&quot;
  </code></pre>
  <p>...and I'm getting this error:</p>
  <blockquote>
  <p>error parsing the input given by the user. Failed with error Unable to infer the source 'D:\Releases\Test\MyApp' / destination 'http://server3:10000/devstoreaccount1/myapp?sv=2019-02-02&amp;st=2020-06-24T03%3A19%3A44Z&amp;se=2020-06-25T03%3A19%3A44Z&amp;sr=c&amp;sp=racwdl&amp;sig=-REDACTED-</p>

  <p>I would have thought my source was pretty clear.</p>
  <p>Can anyone see anything wrong with my syntax?</p>
