You can turn it off, as others have explained, but if you do so, please
don't come back to us and ask us how you can retrieve the data when you've
accidentally saved something and overwritten your data without a backup.

Excel is appears to be backing up files on it's own. Excel appends the
file
name with "Backup of .........xlk" and saves file as an .xlk not a xls
file.
How can I turn this off?
