- Description
- 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.
- XLK files are Microsoft Excel Backup Files, which are created as backup copies of Excel files (.XLS or .XLSX). They contain a copy of the excel file in its original state, and can help to restore a file if the original is lost, damaged or corrupted.
