Append File Output Delimited

I create a File with tFileOutputDelimited (CheckBox: "don't create empty file" is active). Parallel to this with I count the rows with tAggregateRow (this is necessary for the TrailerRow). With tFileOutputDelimited (in AppendMode) I want to write this Trailer to the File.
In same cases the File could be empty. This is ok.
But tFileOutputDelimited (in AppendMode) creates this empty file. How can I prevent this?

Re: Append File Output Delimited

Hi kirsten,
just a short idea: Add an tFileDelete after your job with an condition which will check the number of output lines.
