- Description
- Lotus Worksheet (wk1) is a file type used by the Lotus 1-2-3 spreadsheet application. It is a binary file format used to store worksheets, which can contain numerical and textual data, as well as formulas, charts, and images. It is now considered an obsolete file type and is replaced by the newer xlsx format.
- A DBF (Database File) is a file format that originated with the dBASE database management system, which was one of the first widely used database systems in the 1980s. The format has since been adopted and supported by other database and software applications for storing structured data in a tabular form. A DBF file typically contains a header, which defines the structure of the database, including information about fields (columns) such as name, type, and size, followed by records (rows).
