Actually, OSS has no concept of directory structure. The OSS directory structure is simulated by using a forward slash (/).
If an object whose name ends with “/“, it is recognized as a directory.
You cannot rename an object. However, you can move the object to rename it. To move an object, you must manully upload the object to a new directory and delete it from the original directory. Before deleting a directory, make sure that all objects in the directory are deleted.
