You can transfer the contents of the baskets between accounts by making the bucket public (safer ways to do this). Then, using the aws CLI from another account that you authenticated, run the s3 cp command (this does not require bandwidth):
aws s3 cp "s3: //bucket-source/file.zip" "s3: // bucket-you-dont-own / NewFolder /" - acl bucket-owner-full-control
If you do not add "-acl bucket-owner-full-control" to your s3 line, you will receive an access error message because the target account does not have file permissions:
When calling the ListObjects operation, a client error (AccessDenied) occurred: Access Denied
