Hi @Cadell_Teng,
This is working for me, see below screenshot:
When ever I put a file in the folder it triggers. In event, you have to put the parameters that you wish. Like trigger based on when if the file gets deleted, changed, etc. I recommend that you play around it a little bit using a message box and do what works for you best. Then you can put any process inside of it and it will trigger when that event happens. I hope my explanation was good but if you have further questions let me know.
Happy holidays,
