You don't file the surfaces of nails, you only file across the tips so they are smooth. You will grow fresh nails in a few months, usually less than a year. Until then you can use nail repair, which is a paint that strengthens the nail slightly. Go to youtube.com or search "nail repair" at amazon.com for instructions on how to take care of nails. Or ask at the cosmetics section of a department store at the mall.
