title: Amazon S3 File Permissions, Access Denied when copied from another account
body: <p>I have a set of video files that were copied from one AWS Bucket from another account to my account in my own bucket.  </p>
  
  <p>I'm running into a problem now with all of the files where i am receiving Access Denied errors when I try to make all of the files public.</p>
  
  <p>Specifically, I login to my AWS account, go into S3, drill down through the folder structures to locate one of the videos files.</p>
  
  <p>When I look at this specificfile, the permissions tab on the files does not show any permissions assigned to anyone.  No users, groups, or system permissions have been assigned.</p>
  
  <p>At the bottom of the Permissions tab, I see a small box that says "Error: Access Denied".  I can't change anything about the file.  I can't add meta-data. I can't add a user to the file.  I cannot make the file Public.</p>
  
  <p>Is there a way i can gain control of these files so that I can make them public?  There are over 15,000 files / around 60GBs of files. I'd like to avoid downloading and reuploading all of the files.</p>
  
  <p>With some assistance and suggestions from the folks here I have tried the following.  I made a new folder in my bucket called "media".  </p>
  
  <p>I tried this command: </p>
  
  <pre><code>aws s3 cp s3://mybucket/2014/09/17/thumb.jpg s3://mybucket/media --grants read=uri=http://acs.amazonaws.com/groups/global/AllUsers full=emailaddress=my_aws_account_email_address
  </code></pre>
  
  <p>I receive a fatal error 403 when calling the HeadObject operation: Forbidden.</p>
