Using JITL Job JobSchedulerExistsFile
See also Documentation
The job chain job_chain_file_order_source_poll uses the job JobSchedulerExistsFile to check, whether a file is in c:\temp\input ending with .pdf. If so, for each file found, an order will be created for the job chain job_chain_file_order_source. The file will be removed by the sinks in the job chain.
...
Please note, that you can mix file_order_source and JobSchedulerExistsFile by using JobSchedulerExistsFile in the first node to check, whether the file has been completly written.
