I was wondering if someone could explain how the files in the Audit Trail 11 Catalog folders work?  We have a client who has Audit Trail set to 3 Months of data, but they're finding the catalog folder just continually keeps adding more "Archive#" folders, but never actually cleans them up.  So they have folders in here with audit data older than 3 months (5 or 6 currently).  How exactly does the new Audit Trail Reporter cleanup and remove outdated information?  Does it hit a certain age and then move things to the archive folder?  Or does it go based on size?  Any overview of the inner workings and cleanup schedule would be appreciated, thanks!
