Dennis, This is a good question for a HR pro but in my experience once you hand over resignation info the company’s goal is to get you out of the position as soon as possible. In some cases sooner rather than later especially if the it's based on hostile terms. I would ask someone in management or HR before removing or copying files just to avoid future repercussions. I’m sure they have their own process of wiping data but it’s safer to check beforehand. Sorry to hear you’re thinking of leaving the job… hopefully for a better one!
