This job removes documents from trash can periodically. Once a content has been deleted from trashcan, ContentStoreCleaner job moves it to Deleted Content Store and change node state to deleted in database 14 days after. NodeServiceCleanup job remove the node from database 30 days after, but in the end the file is still living in Deleted Content Store. This addon will purge from Deleted Content Store (usually at ${alfresco}/alf_data/contentstore.deleted) these abandoned files.
