Filename at the very top of Microsoft Excel Window

[Guest]

At the very top of the Excel window where you have the Microsoft Excel icon,
it contains the words 'Microsoft Excel - filename'. Until yesterday it was
showing the words 'Microsoft Excel - ' with the filename. Yesterday it
contained the '.xls' at the end of the filename and today it only contains
the filename with no file extension. I have an automated program that looks
for the filename with the file extsnsion to close down excel and it's not
working.

How do you control the display of the file extension or not?

Hi,

An unsaved file will not have an extension.

You've changed the settings in Windows Explorer for extensions for known
file types. Now they are hidden.
