I have been searching and have Not found an answer yet so I thought I would ask.  I don't know What version I am using but simply want to know is there a way  to only send a file like a pdf if it goes above a certain size? I have a report that only occasionally has information in it. I would like to be able to email it only when the report actually has results so as to keep from sending out Needless emails that people will eventually ignore.
