2.2.2.1 Folder Redirection Section
The file MUST contain another section with the SectionID folder redirection. This section MUST contain zero or more key-value pairs, called GUID-Groups, in the following format: The key is a string representation of a GUID identifying a user profile folder, and GUIDs of well-known folders are listed in the table in section 1.9. The value MUST be one of two representations specifying either a single SID or a list of SIDs, as specified in the sections that follow.
The client-side plug-in MUST determine what per-GUID section to interpret and pass to the folder redirection subsystem, by determining what security group the user belongs to. If the user belongs to more than one security group, the client-side plug-in MUST use the first matching GUID-Group that appears in the section.
