Whenever you create a new file or folder, the Windows operating system will assign it a set of default permissions. These are called Effective Permissions. The user who creates the file or folder can also change and assign specific permissions to it. This article will discuss in brief what are Effective Permissions for Files and Folders, in Windows and tell you how to view them, for any user or user group.
Effective Permissions for Users and User Groups
As mentioned, Effective Permissions is a set of permissions of the file or folder for any user or user group. To secure the contents of the user, Windows sets some permission for each file or folder object. It grants users specific user rights, that will allow the user or user group to read, modify, delete, etc the object. The minimum permission is the Read permission.
This chart, sourced from Windows Help, lists the access limitations for each set of the special permissions.

All or some of the checkboxes will automatically get selected. These will indicate the effective permissions of the particular user or user group for that file or folder.
Effective Permissions Tool
If you want to find out what permissions a user or group has on an object, you can use the Effective Permissions tool. It calculates the permissions that are granted to the specified user or group. The calculation includes the permissions in effect from group membership and any permissions inherited from the parent object. It looks up all domain and local groups in which the user or group is a member.
