Thank you for the help! I think folderwatch is actually the easiest way to do it. And it's works.
Eventscripter:
I'm just learning Python and can't write the Eventscript myself, yet. But if anyone can write the code, I think it's a valuable contribution to the Eventscripts pinned thread.
Even though the thread moved totally off topic, I still think some examples in the documentation of the API would be helpful.
Thread is SOLVED. :D
