title: How to set ACL of all files in a folder in S3
body: <p>I want to give read permission to all the files inside a folder in S3 using Java. I am doing folder upload using TransferManager but I did not find any API to set ACL on the directory level</p>
  
  <p><code>MultipleFileUpload upload = transferManager.uploadDirectory(bucketName, uploadDirectory, new File(folderName), true);</code></p>
  
  <p>I know that I can set ACL of an S3 object using:
  <code>s3.setObjectAcl(bucketName, key, acl);</code></p>
  
  <p>But I want to do it on all files at once in a folder. Is there any way to do it?</p>
