It is created in the workspace directory. It is created by the application whenever it detects that a newer rulebase is ready on our servers. This file is created even if the update script mechanism is turned off.

The idea is that some other program (or scheduled task) can check for the file and download the rulebase if the file exists. That task should delete the file if it succeeds in downloading the rulebase file.
