SUMMARY

The file name extensions for backup files that you save with the Create Backup option in Microsoft Word 7.0, Microsoft Word 97, Microsoft Excel 7.0, or Microsoft Excel 97 are different from the file name extensions for earlier versions of Word and Microsoft Excel.

The following table lists the file name extensions for backup files that you save in Word versions 6.0, 6.0a, 6.0c, 7.0, and Word 97; Microsoft Excel versions 5.0, 5.0c, 7.0; and Microsoft Excel 97. 
Program                               File name extension
---------------------------------------------------------

Word 6.0, 6.0a, and 6.0c              .bak

Microsoft Excel 5.0, 5.0c             .bak

Word 7.0 and Word 97                  .wbk

Microsoft Excel 7.0 and

In addition to using different file name extensions for backup files, Word 7.0, Word 97, Microsoft Excel 7.0, and Microsoft Excel 97 also add "Backup of " to the beginning of the backup file name. For example, a backup copy of a file named "Weekly Report.xls" would be named "Backup of Weekly Report.xlk" in Microsoft Excel 7.0.
