When I try to rename a file name it says:
"If you change a file name extension, the file may become unusable. Are you sure you want to change it?"
If I click yes I can't open the file. It never used to do this so what's happened?

That would be because you are changing the whole file name, along with the file type extension like .exe, .xls, .doc. If you change that then Windows has no idea how to open that file or what program to use to open it with. So just change everything before the . .

First, what file extension is the file? and what did you change to?

The message will only occurs if you rename file name with View file extension option being enabled.

If you do not wish to view file extension, you can do the following to disable it.

Click Start, open My Computer, select the Tools menu and click Folder Options.
Select the View Tab.
Uncheck: Hide file extensions for known file types.
Click Apply and OK to exit.
