A file protection method, to resolve a problem that privacy of a file cannot be ensured by manually hiding the file or manually encrypting the file, is presented. The method includes obtaining, by a terminal device, a target file; determining, by the terminal device, whether the target file satisfies a preset file condition; when the target file satisfies the preset file condition, determining, by the terminal device, whether the target file satisfies a corresponding preset protection condition; and when the target file satisfies the preset protection condition, applying, by the terminal device, a corresponding protection solution to the target file. The embodiments of the present disclosure further provide a corresponding file protection apparatus.
