Overview

You can set access permissions of folders in the COS console, so that specified users can perform specified operations on the content of the folders. You are recommended to follow the principle of least privilege when configuring permissions to protect your data assets.

Note：

COS stores objects in a flat structure with no traditional folder concept. In order to make COS customary, we turn an object into a "folder" by suffixing it with / in its key. In fact, a "folder" in COS is an object with a storage capacity of 0 KB.

Folder permission is essentially access permission at the object level, which takes precedence over the bucket access permission. COS supports two types of object permissions:

• Public permissions: inherited permission, private read/write, and public read/private write. For more information on public permissions, please see Access Permission Types.
• User permissions: the root account has all the permissions of the object by default (i.e., full access). In COS, sub-accounts can be added to read/write data, read/write permissions, and have the full access.
