I also noticed there is a mapping table to map packagte_id to the folder_id for the package.
Does this do something different than cr_folders.package_id? It seems that some packages use a table to map package_ids to a folder, but this ability is built into the content repository.
Dave, I only created that mapping table as I noticed other packages were doing the same. If cr_folders.package_id already does this, then I will make the required change.
