How do I set up access to a single directory inside an Amazon S3 bucket?

Question

Amazon Web Services

I have an Amazon S3 account with multiple buckets. There are several directories in one bucket. The task is to set up access for the user to only one specific directory in a specific bucket with the ability to read / write.
I tried this one, but it doesn't work:

{
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "s3:ListAllMyBuckets",
            "Resource": "arn:aws:s3:::*"
        },
        {
            "Effect": "Allow",
            "Action": "s3:*",
            "Resource": [
                "arn:aws:s3:::bucketname/catalog",
                "arn:aws:s3:::bucketname/catalog/*"
            ]
        }
    ]
}

I would be grateful if someone could tell me how to solve this problem.
