title: Talend: How to integrate multiple files in folder?
body: <p>I'm a beginner with Talend.</p>
  <p>I would like to integrate 4 files.</p>
  <p>For example,
  In my folder, there are files like</p>
  <pre><code>aaa_yyyymmdd_1.csv , aaa_yyyymmdd_2.csv , aaa_yyyymmdd_3.csv  , aaa_yyyymmdd_4.csv
  
  aba_yyyymmdd_1.csv , aba_yyyymmdd_2.csv , aba_yyyymmdd_3.csv , aba_yyyymmdd_4.csv
  </code></pre>
  <p>... (front part of the filename is dynamic with the date)</p>
  <p>And these files have the same schema like
  ID; Name; Location; Data(float);</p>
  <p>I would like to integrate samename_samedate_1 , _2, _3, _4 files and make it like</p>
  <pre><code>ID; Name; Location; Data1; Data2; Data3; Data4;
  </code></pre>
  <p>Can you tell me how to design the job for this?
  Thank you!</p>
