I am trying to track down the scheme of the database. How is the ost_file & ost_attachment & ost_ticket tables all linked?I have my antivirus reporting a trojan that I need to get rid of, I can delete the file however I do not want to delete the file without first getting rid of the database entries. Second question, is there a database cleanup script of some sort which I can run for when things are deleted?Thanks,-Tom
