Based on the information in all the tables that you received, what are Yvette s effective permissions on the Brochures folder
Summary
You use NTFS permissions to specify which users and groups can access files and folders, and what they can do with the contents of the files or folders. NTFS permissions are available only on NTFS volumes. It is possible for multiple sets of NTFS permissions to apply to a user for a particular resource. A user s effective permissions for a resource are the sum of the NTFS permissions that you assign to the individual user account and to all of the groups to which the user belongs. To assign or modify NTFS permissions for a file or a folder, you use the Security tab of the Properties dialog box for the file or folder. You can use the Advanced Security Settings dialog box to configure specific permissions for a user or group. You should also note the following:
You cannot assign a user ownership of a file or folder; you can only give a user permission to take ownership. By default, subfolders and files inherit permissions that you assign to their parent folder. You can prevent a folder from propagating permissions to subfolders and items in the folder. You can also prevent a file or subfolder from inheriting permissions from its parent folder.
You should be aware of the following behaviors when you copy or move files and folders to which NTFS permissions are applied:
When you copy files or folders from one folder to another or from one volume to another, the object takes on the permissions of the destination folder. When you move a file or folder within a single NTFS volume, the file or folder retains its original permissions. When you move a file or folder between NTFS volumes, the file or folder inherits the permissions of the destination folder.
