You wouldn't rename a file in Excel. You would normally do it through Windows Explorer. However when opening a file in Excel, when the Open Dialog is open, it is possible to click on a file and rename it or do it through the Tools menu in the Open Dialog box. However you would rarely use that approach. The other thing you can do is use Save As and choose a new name, which will give you a copy and retain the old file.
