Can anyone tell me what the dlfp tables are for. I inherited an existing DNN site and for purpose of development I've created a clone of the site on my development server. I've gotten most of it functioning in the dev environment but I'm running into an issue with a custom built module that uses raduploader to upload images to the server for processing later. The error has to do with Violation of PRIMARY KEY constraint 'PK_dlfp_Folder'. I understand what the error means and how to fix it. I want to know more about what these dlfp tables and procedures are used for and where they came from my other DNN installs do not seem to have them. Any direction would be very appreciated

The site I'm referencing was an original 7.00.06 Pro install back in 2013. It has been upgraded to Evoq 8.1.

I used a bacpac file to move the db.  I wrote a powershell script to export the db then import to the new server.
