[Vtigercrm-developers] Use of user_privileges directory

[Manilal K M]

Hi all,
  Please somebody give information about the user_privileges in
vtiger5. I found two files like
#1. index.html
#2. sharing_privileges_2.php
#3. user_privileges_2.php
#4. sharing_privileges_1.php
#5. user_privileges_1.php

I searched the documentation, but no information. Is these files
dynamically created or statically created when the user is created?

regards
Manilal
