I already know that in computing in general, registry is the main data structure for paths (whether as a table in DB or a as a standalone DB).
In the case of Drupal, I saw two tables in the DB's. When is "registry" and the second is "file_registry".
While I understand that file_registry table holds paths for files, I wonder what are the main kinds of paths that the "general" registry table holds, and thus what are the main differences between them. I hope a Drupal developer who have dived into these SQL files could explain the main differences,
