amazon s3 - How to make 10,000 files in S3 public

Question

I have a folder in a bucket with 10,000 files. There seems to be no way to upload them and make them public straight away. So I uploaded them all, they're private, and I need to make them all public.

I've tried the aws console, it just gives an error (works fine with folders with less files).

I've tried using S3 organizing in Firefox, same thing.

Is there some software or some script I can run to make all these public?

You can generate a bucket policy (see example below) which gives access to all the files in the bucket. The bucket policy can be added to a bucket through AWS console.

{
    "Id": "...",
    "Statement": [ {
        "Sid": "...",
        "Action": [
            "s3:GetObject"
        ],
        "Effect": "Allow",
        "Resource": "arn:aws:s3:::bucket/*",
        "Principal": {
            "AWS": [ "*" ]
        }
    } ]
}

Also look at following policy generator tool provided by Amazon.
