title: Copy files between folders in the same S3 bucket by using cp
body: <p>I am trying to copy files between folders in the same S3 bucket by using the following:</p>
  
  <pre><code>aws s3 cp s3://bucket/folder1 s3://bucket/folder2 --recursive
  </code></pre>
  
  <p>It halts after copying some files.</p>
  
  <pre><code>Completed xxxx part(s) with ... file(s) remaining
  </code></pre>
  
  <p>Sometimes it copies 2k sometimes 4k. I have more than 30k files.</p>
  
  <p>Is there a limit to file copy? How can I copy large number of files?</p>
