Hello!
I’m very interested in an UploadReference table. We are in a situation where we have a lot of uploads in plugins that would be considered to be orphan uploads. Our solution is simply to turn off the clean_up_uploads. I checked the other day and we now have 10GB of orphan uploads that would need to be removed manually with some script that also figures out if we reference any of them in our plugins. A solution like the one discussed here would help out a lot for us.
