推荐答案

Amazon S3 中没有文件夹之类的东西.它是一个平面"文件系统.您可以越接近文件夹，在您的文件名中添加前缀，例如 foo/bar/filename.txt.尽管一些 S3 工具会向您显示内容，就像它们包含在文件夹中一样，但 S3 上不存在这种概念.

There is no such stuff as folders in Amazon S3. It is a "flat" file system. The closer you can get to folders is adding prefixes like foo/bar/filename.txt to your file names. Even though several S3 tools will show you stuff as if they were contained inside folders, this concept does not exist on S3.
