I was searching online earlier today to try and find out how to delete files permanently. My boss has asked me to clean up the company computers, but wants it done to a level that the files can never be recovered.I do not know why he wants that level of security, as the databases only hold records of vehicle numbers, but he is the boss. Until I started doing the research, I was not aware that a deleted file the normal way, was not actually deleted. I wonder how many do not know that.
