To delete permissions for a user or group, go to the Manage Permissions page, select the check box next to User/User List and select Delete. All of the selected users and lists will have their permissions removed. After permissions are removed, the users can no longer access the item.
If the user is granted read permission, the link will work .
When you edit or add permissions to a parent folder, you have the Overwrite option, which forces all files and sub-folders to inherit these permissions. For example, if the read and write permissions are added to the folder and you select Overwrite, all permissions to items within that folder are reset to read and write.
After content is added to the Content Collection, permissions must be granted to make the content accessible to users and groups of users. Permissions allow users to perform certain actions on items in the Content Collection, that range from read-only access, to editing, managing and removing content.
Some users have default permissions to specific folders. In this case, various permissions are automatically granted to specific folders.
Any user with Read and Manage permission on a file or folder may grant permissions to other users and user lists.
Users can organize folders in a way that allows them to manage permissions by folder, rather than by file. For example, create a folder that contains all files used in a group project. Then, the entire folder may be shared with the group members, rather than trying to manage permissions on separate items stored in different folders.
When users add folders and files to the Content Collection, they need to keep in mind which users and user lists the content will be shared with. Try to create folders for all items that are to be shared with the same users. When items shared with the same users are spread out among different folders, it may become difficult to manage.
Files are available automatically to the user that added the file but must be shared if other users are to view the item.
When users add or edit permissions on a parent folder, they have the option to force all files and subfolders to inherit these permissions. For example, if the read and write permissions are added to the folder, and an item within the folder has read, write, and remove permissions, remove permissions are removed from the file.
