The primary function of a nail file is to shape the nails. Nail files are designed to refine the edges and surface of the nails, allowing for the desired nail shape—whether it be square, round, or oval. By using a nail file, a nail technician can create smooth edges and precise contours, which is essential for both aesthetic appeal and nail integrity.

While cleaning the nails, enhancing color, and removing cuticles are important aspects of nail care and maintenance, they are not the main purpose of using a nail file. Cleaning is typically done with brushes or soap and water; color enhancement involves polish, gels, or acrylics; and cuticle removal is performed using specialized tools such as cuticle pushers or nippers. Thus, the nail file's primary function distinctly centers on shaping rather than these other tasks.
