ishredder application topic

I tried ishredder application, which I think its application only to delete empty storage, which occurs even delete all my internal and external storage. i lost all of my data internal and external storage :crying:, but my application is already installed are not deleted. I've tried using the hexamob application but have not been successful.

does anybody know how to restore lost files? I need some data that has been missing from my storage..
thank you
