Where is stored the Folder label registry location?

Question

When I put a red label on a File that has xmp metadata, I can retrieve these values later and this will be stored in the file or in a side-car xmp file.
But Folder can't have xmp.
In this case, where is stored this info about the color label of a Folder? Only in cache? Is there a hidden file ( like, for example ".Bridgesort" hidden file for manually sorted items)
I noticed that I I label a folder in a common accessed network from computer A, I can retrieve that value from another computer B by rebuilding the cache parent folder of the labeled folder.
It can't be the file C:\Users\[username]\AppData\Roaming\Adobe\Bridge CS6\Cache\data\store because it is inacessible from other computers on network.
So is must be some hidden file on the same directory of the labeled folder.

Answer 1

Found it.
Its an hidden xml File created from Bridge when I use labels or ratings on children folders.
It is called ".BridgeLabelsAndRatings"
to get it from bridge, just try to use this
Folder([myPath]).getFiles("*.BridgeLabelsAndRatings"); // the name works like a long extension file (the dot in the beginning is important)
and this is an example.
<?xml version='1.0' encoding='UTF-8' standalone='yes' ?>
<bridgedata version='1'>
  <labels version='1'>
  <item key='_d_10772009' label='Select'/>
  </labels>
  <ratings version='1'>
  <item key='_d_10772012' rating='1'/>
  </ratings>
</bridgedata>
This is updated from others computer over the same local folder network only when cache folder is recreated.
