This document provides an in-depth explanation of how collaborator permissions are inherited in Box. This information applies to both shared personal folders and project directories.
Due to the way in which permissions are inherited within a single folder directory in Box, provisioning access to collaborators can become quite complicated. For this reason, understanding how permissions are inherited is critical to creating an effective folder structure and ensuring that collaborators have appropriate access to your shared files and folders. In this article, we will review basic terminology when describing folder directories, provide textual and illustrated examples of permissions inheritance within a folder directory, and offer advice on how to structure and name folders when provisioning access to collaborators.
Before we can discuss permissions in Box, it is necessary to understand the terms commonly employed to describe folder structures. In this section, we will define four important terms that will be used throughout the rest of the article: directory, root level, parent, and child.
When you log into Box to view your files and folders, you are initially viewing only your highest level folders, i.e., those that exist at the root level.
- Tip: A good way to remember the meaning of a root level in a folder structure is to imagine your folder structure as an inverted tree. The root of the tree is at the top, and each level of subfolders branches off from the root.
Folders are often referred to as directories, with the two terms being interchangeable. When a folder contains one or more subfolders, the first folder is said to be the parent of its subfolders. These subfolders in turn are referred to as children of the parent folder. Many times, a folder will be both a parent and child, that is, it is contained within a parent folder and is a parent to its own child folders.
Pictured below is a very basic folder structure, which consists of a single folder (A) at the root level, which is a parent to two additional child folders (B and C):
In the example above, only folder A would be visible from the "All files and folders" view in Box. Only once you clicked on folder A to view its contents would you see both folders B and C.
In Box, any collaborator permissions set on a parent folder are automatically inherited by all child folders. If these child folders are also parents to another level of child folders, these permissions will be passed down to that folder level; this will continue for the entire folder directory.
This inheritance is illustrated below. The folder structure shown is identical to the one above; the only difference is that the folders below are identified as collaboration folders rather than personal folders. In this example, "Alex" was given Uploader access to folder A. Because folder A is also parent to folders B and C, Alex also inherited Uploader access to these two folders. In contrast, "Billy" and "Chris" were granted individual access to folders B and C, respectively. In this instance, neither Billy nor Chris would be aware of the existence of folder A, so when viewing all files and folders within their Box accounts, they would see either folder B or C as the root level collaboration folder.
- Note: In all the examples that will follow, names written in bold indicate the folder to which access was originally designated, and unbolded names signify access that was inherited from a parent folder.
