File design is the process of organizing and structuring data in a computer file so it can be stored, accessed, and managed efficiently. A well-designed file ensures data integrity, accuracy, and quick retrieval. It involves deciding the file type, record structure, field types, size, and format. Files can be sequential, indexed, or direct, depending on how data will be accessed. File design also considers security, backup, and future expansion. Examples include customer databases, payroll records, inventory files, and student records. Good file design reduces redundancy, prevents errors, and supports smooth operations.
