SSIS - how to fail the package when the for each loop container finds no files

Hi,

I have created a For Each Loop Containers to loop through the files in
the directory and process them. If it does not find any files in the
directory it should fail the package. However it does not do so by
default. It reports success. How do I change this behavior. I would
like it to fail the package if it does not find any files.

Help is greatly appreciated
