我所做的是创建一个新文件夹，并将旧的files对象移动到新文件夹。

下面是你如何在。net中使用S3 .NET SDK:

var client = new Amazon.S3.AmazonS3Client(_credentials, _config);
client.CopyObject(oldBucketName, oldfilepath, newBucketName, newFilePath);
client.DeleteObject(oldBucketName, oldfilepath);

附注:尽可能使用“异步”版本的客户端方法，尽管我没有这样做是为了可读性

要重命名文件夹(从技术上讲，文件夹是一组对象，以公共前缀作为键)，您可以使用aws CLI move命令带——recursive选项。

aws s3 mv s3://bucket/old_folder s3://bucket/new_folder --recursive

S3DirectoryInfo有一个MoveTo方法，它将把一个目录移动到另一个目录，这样移动的目录将成为另一个目录的子目录，其名称与原来的目录相同。

下面的扩展方法将一个目录移动到另一个目录，即移动的目录将成为另一个目录。它实际上所做的是创建新目录，将旧目录中的所有内容移到该目录中，然后删除旧目录。

public static class S3DirectoryInfoExtensions
{
    public static S3DirectoryInfo Move(this S3DirectoryInfo fromDir, S3DirectoryInfo toDir)
    {
        if (toDir.Exists)
            throw new ArgumentException("Destination for Rename operation already exists", "toDir");
        toDir.Create();
        foreach (var d in fromDir.EnumerateDirectories())
            d.MoveTo(toDir);
        foreach (var f in fromDir.EnumerateFiles())
            f.MoveTo(toDir);
        fromDir.Delete();
        return toDir;
    }
}

s3中的文件夹结构有很多“问题”，似乎存储是扁平的。

我有一个Django项目，我需要重命名文件夹，但仍然保持目录结构不变，这意味着空文件夹也需要复制并存储在重命名的目录中。

aws cli很棒，但cp或sync或mv都没有将空文件夹(即以'/'结尾的文件)复制到新的文件夹位置，所以我使用boto3和aws cli的混合来完成任务。

或多或少我找到重命名目录中的所有文件夹，然后使用boto3将它们放在新位置，然后我用aws cli对数据进行cp，最后将其删除。
