Folder Redirection is a User group policy. This means that a user for whom you configure folder redirection must have a group policy linked to some folder structure where their user object is subordinate, such as a site, domain, or organizational unit.
Once you create the group policy and link it to the appropriate folder object, an administrator can designate which folders to redirect and where To do this, the administrator needs to navigate to the following location in the Group Policy Object:
User Configuration\Windows Settings\Folder Redirection
In the Properties of the folder, you can choose Basic or Advanced folder redirection, and you can designate the server file system path to which the folder should be redirected.
The %USERNAME% variable may be used as part of the redirection path, thus allowing the system to dynamically create a newly redirected folder for each user to whom the policy object applies.
