Can we withhold personnel files from terminated employees? How about paychecks?

Q: “We are a private company and a terminated employee has sent a written request to view their personnel file. Do we have to oblige? Second question: The terminated employee has not returned uniforms... can we withhold the last paycheck? Finally, the terminated employee had previously paid for a patio door from the company that is still here... if the employee doesn’t return the uniforms, can we keep the door?” - Storme, Arkansas
