1) I just meant small machine, actually smaller than my many years old desktop! 1GB user memory is considered "small". A user who has a 1TB log file would normally be a commercial user. A commercial system will have more than 1 GB for user in this type of case.
2) No offense intended re: where did file come from? That meant from what application, etc. Not any personal info needed. Maybe this thing is from an input to a commercial DB? I dunno know. Maybe a report from this DB is more appropriate.
3) I don't know what #3 means.
In any event, no offense was intended!
