I've been trying to find the "Tutorial" which was mentioned to be a pdf file but could not. Can't find downloadable "Quick Guide" either. My question is if I move a file like Word or Excel from the hard drive to a USB drive, is that file then securely removed from the hard drive or should I still be concerned? If yes, how do I fix that since I will no longer be able to find it in the hard drive? Sorry, naive question.
