Sorry for the long description but I wanted to be as clear as possible.

Request that _DGNFile be populated with the full path of the CAD file that is being opened [and when a new file is being opened the configuration variable is reloaded and can be evaluated by the pre-processor flow directives], and the full path be accessible so it can be queried during read/resolve phase of Configuration pre-process using Flow Directives, Logic and Operators and resolved prior to Application runtime [as it is resolved at present].

Loading the _DGNFile configuration variable would greatly enhance configuration operations opportunities and load events based decisions on the file type, path, device or URL and effect subsequent configuration events.

This will allow administrators to make configuration and application decisions on a wide variety of trigger events including file type, file name, device name, file locations… which in turn can determine the end user experience including GUI, resources, scripts, configuration settings, attachments, WorkSets and other aspects of the application.

To be honest I didn't know it wasn't being loaded in the pre-processor because I have always used this variable at application Runtime, thinking it was being loaded in configuration. I am really surprised nobody has requested this change over the past decade?

Seeing that _DGNFile is also supposed to be a Root Level configuration variable, but is not populated at System Level is also a surprise.

Hopefully this can be changed in the next or subsequent builds?
