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.

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.
