Start Autoit script when user open a specific file

[Rapidnxit]

Hi! As I have write in the title, I'd like to make a script that wait until a specific file is opened(double click on it), for example an image or a pdf document, and than it visualizes a simple box message.

I'm new in Autoit programming and I did not find anything useful for this purpose yet.

Thanks!
