title: Batch: reading textfile containing list of files with enviromental variables (e.g.: %appdata%) won't get "resolved" when used
body: <pre><code>for /F "tokens=*" %%A in (.\a.config) do (
  echo "%%A"
  copy /y "%%A" .
  )
  </code></pre>
  
  <p>If a line in a.conf contains an environmental variable I just get that echoed (e.g.: "%appdata%......") not the absolute path. How to resolve? </p>
