Thanks for the suggestion. I hope it works for me too. I will surely do C/Windows/USB_Vibration/ and delete all files and will see the result. But I can't do it right now because I am writing an essay assignment with the help of this Essays on Historical Figures, Free Examples, Topics, Titles, Outlines | TopEssayWriting website and when I am done with my work after that I will do as you told how you solved the problem.
