title: Copy a set of files using ADF
body: <p>I have 10 files in a folder and want to move 4 of them in a different location.
  I tried 2 approaches to achieve this -</p>
  <ol>
  <li>using lookup to retrieve the filenames from a json file- then feeding it to a for each iterator</li>
  <li>using metadata to get file names from source folder and then adding if condition inside a for each to copy the files.</li>
  </ol>
  <p>But in both the cases, all the files in source folder gets copied.</p>
  <p>Any help would be appreciated.</p>
  <p>Thanks!!</p>
