title: Merging multiple csv files in cmd
body: <p>I have multiple csv files of large size in a folder, say </p>
  
  <pre><code>file1.csv
  file2.csv
  file3.csv
  combine.csv 
  </code></pre>
  
  <p>And if I have to combine (append) all of them using cmd, I know that I have to use </p>
  
  <pre><code>copy *.csv targetfile.csv
  </code></pre>
  
  <p>My question is what if I have to combine the csv files which has the name <strong>"file"</strong> in it which are <code>file1.csv, file2.csv, file3.csv</code> in this case.</p>
