文件 (wén jiàn) literally combines 文 (wén), meaning 'writing' or 'text', and 件 (jiàn), a measure word for discrete, countable items — together, they mean 'document': any written, printed, or digital material that conveys information, records data, or serves as official evidence. It’s a neutral, formal term widely used in offices, schools, government, and computing.

In modern contexts, 文件 most commonly refers to digital files — like Word documents, PDFs, or spreadsheets — but it also covers physical papers such as contracts, certificates, reports, or letters. Unlike more specific terms like 合同 (contract) or 报告 (report), 文件 is a broad, umbrella noun; it emphasizes the functional role of the material as an organized unit of recorded information, not its content type or purpose.
