- Select Check for File Modification check box if you want to process the files that are modified after creation. This option is enabled only if On FileCreated option is selected in the Trigger Type drop-down list box.
Select Run Initial Load check box if you want to process the files that are created when the event is not active. This option is enabled only if On FileCreated option is selected in the Trigger Type drop-down list box.
After the activation of the event, for the first time, the system processes all the files that exist in the base folder location,irrespective whether they were processed earlier or not. However,and and for subsequent activations, only the unprocessed files are processed each time.Select Don't Process Duplicate Files check box if you don't want to process the same file again.

Select the Secure check box , if the File Event is secured, that is, username and password are required to access it.
