Is it possible to fire a stored proc when a file is created? (WMI Alert)

I would like to execute a store proc when a file gets created each day, the file gets deleted as part of the proc.

Can I do this  using SQL alert - WMI event alert? I imagine creating a job which runs the proc and the job will run the proc. The alert would start the job on file creation.

Is this possible, can anyone help with a sample query? What should I use as the Namespace?

Thanks
