When documents are deleted there is no record in the database of the object's original location in the file vault. If the document was deleted by accident then the only way to find the orphaned content is to manually search through the file vaults which is very time-consuming. If auditing is set to record the 'delete' event then Windchill records a variety of information about the documents that have been deleted...except for the one piece of information that would be really useful - where the original content was stored. If it's possible, I suggest recording the original file location in the audit report. It would make life so much easier.
