I hope that the file list of the Directory can include the GUID of the objects if the files in the Directory have GUID.
One of the examples is "...\Neighborhoods\Nxxx\Characters".
Also, the data in the files in "...\Neighborhoods\Nxxx\Lots" are not easy to comprehend, and some of them are "unk:0xXXXXXXXX", therefore I don't know whether the files have GUID.
