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.
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.
