Well, I verify that the file is finished writing before I queue it. These can be very large plot files - is it possible it is not finished queueing before I try to delete it?

You suggestion about attempting to open it before deleting will work, I'm sure. Would it be worth your while modifying the class to provide a property to indicate whether qeuing is complete?

IAC - thanks for the workaround - and the class!!!!
