I am facing the problem, that I want a trigger only fired when a file is created and the content of more than zero bytes.

Is there a way to configure the trigger accordingly or build a job flow logic that executes only when a none zero byte is created.

Moving topic.

Not directly. But you could use a List files Task and check only include files that are zero bytes. Then, you could create an Email Task. On the Email Task you attach a Condition. The Condition checks the output of previous Task. If output is not empty it means that a file has been found.

You can check out File Triggers and Variables and Conditions in the Tutorials page:
