Hooks Cucumber

Hi all
I want to clean up all the previous run screenshots

so i want to run(only once not for every scenario or feature file) a
batch file before my tests run.
i am using system " start …/…/results/clean_screenshots.bat" in my
hooks file but it runs for every scenario any suggestions
Thanks
Kiran
