2.2.2.2.4 RelativePath Key

The section MUST contain at most one key with the constant string RelativePath if the flag 0x00000002 is set, as defined in section 2.2.2.2.1. This key indicates to the folder redirection subsystem that it MUST treat the value as a relative file system path, using the backslash character "\" as a directory delimiter. The subsystem MUST determine the redirection destination as the concatenation of the destination path of the parent folder (as specified by the ParentFolder key) and the relative path indicated by the value of this key. The RelativePath key value MUST NOT start with a backslash character "\".
