Lotus 1-2-3 Spreadsheet (wks) is a file type used for storing spreadsheet documents created with the Lotus 1-2-3 software. It is a proprietary format developed by IBM, and was the predominant spreadsheet software during the 1980s and early 1990s. The files typically contain data organized in rows and columns, as well as formulas and calculations.
DIF stands for Data Interchange Format that is used to import/export spreadsheets data between different applications. These include Microsoft Excel, OpenOffice Calc, StarCalc and many others. It stores data contained in a single spreadsheet which is the only limitation of this file format.
