title: How to use wildcards in filename in AzureDataFactoryV2 to copy only specific files from a container?
body: <p>So I have a pipeline in AzureDataFactoryV2, in that pipeline I have defined a copyActivity to copy files from blob storage to Azure DataLake Store. But I want to copy all the files except the files that have "-2192-" string in them.</p>
  
  <p>So If I have these files:</p>
  
  <pre><code>213-1000-aasd.csv
  343-2000-aasd.csv
  343-3000-aasd.csv
  213-2192-aasd.csv
  </code></pre>
  
  <p>I want to copy all using copyactivity but not 213-2192-aasd.csv. I have tried using different regular expression in wildcard option but no success.</p>
  
  <p>According to my knowledge regular expression should be:
      <em>[^-2192-]</em>.csv</p>
  
  <p>But it gives errors on this.
  Thanks.</p>
