ApplicationXtender Delete Images

Hello!  We have had ApplicationXtender since 2000 and have done very little purging.  We have a few cabinets that contain millions (one has 79M) images.  We really need to get it cleaned up.  We have attempted to create queries and delete from the result set, but it only deletes up to about 16,800, then crashes.  It will take several years deleting at that rate.    We really would like a quick and dirty way of deleting the old images, if possible.  Any suggestions would be greatly appreciated.  Currently on AppX 6.5

Thank you!
