Hi Noelle - It looks from the photos like you got a little vigorous with the file, and riled up the skin, which was probably callused. Your body just needs to finish shedding and replacing the old skin. Since you are worried about the look, and trying (possibly) too many different things to try to make them look "normal" - this is just prolonging the irritation.
I would suggest you try massaging them with a nice oil after you wash them in mild soap each evening, then putting on cotton socks to keep the oil in contact. Baby oil, or even vegetable or olive oil from the kitchen are good choices. In the morning, just rub it in.
In the future, be more gentle with yourself - perhaps use a sugar/oil or salt/oil scrub to remove the rough skin. If you need something more aggressive, try a pumice stone or an abrasive pad like is used in a salon. Walking in beach sand is also excellent for wearing down rough spots! These take longer than metal, but are gentler on your skin.

Can you try this for the weekend and let us know if it helps?
Sue
