How it's used

Beyond the literal action of using a tool to smooth surfaces, this word is frequently used in casual settings to describe the act of shaping or refining something, such as fingernails or metal edges. It implies a repetitive, grinding motion rather than a single cut. When used in a metaphorical sense, it can sometimes suggest the tedious process of refining a rough draft or a project.

Examples

Please help me file this wooden board until it is smooth.
She really likes to file her own fingernails.

Common mistake

Learners often confuse this with 磨, which is a broader term for grinding or rubbing. While 磨 can apply to almost any friction-based smoothing, 銼 specifically implies the use of a file or a similar abrasive tool.
