如何编写 S3 存储桶策略以在 s3 存储桶中的文件夹内立即禁用批量删除但允许用户单独下载？

Question

I have an S3 bucket with the following structures.

/
|-- folder1
|   |-- img1.jpg
|   |-- img2.jpg
|   |-- img3.jpg
|   `-- somedata
|       `-- file.mp3
`-- folder2
    |-- img1.jpg
    |-- img2.jpg
    |-- img3.jpg
    `-- somedata
        `-- file.mp3

Now, I don't want any user to delete the contents of any folders ie folder1 or folder2 at once, but if they want they can do it individually, one at a time. Like delete folder1/img1.jpg , folder1/img2.jpg but should not be able to select img1.jpg , img2.jpg , img3.jpg , somedata/file.mp3 from the console and delete in one go.

There is no command in Amazon S3 to "delete folders". Each object must be deleted individually.

Even if you use a utility such as the AWS Command-Line Interface (CLI) , it simply loops through the objects and deletes them one-at-a-time.

So, users cannot actually "delete folders". Thus, it is not possible to 'disable bulk delete' since there is no bulk delete capability. (Unless you use Amazon S3 Lifecycle.)
