Thanks a lot, the problem with adding the extension outside the  
choose file dialog is that if the file already exist it then bypasses  
the "Replace File" Dialog that is displayed inside the choose file  
dialog. e.g.

Choose File Dialog, User enters "Fred"   (Fred.rev already exists),  
but since the .rev extension is not added until after the dialog is  
dismissed the "replace file" warning dialog is not shown. Then the  
user script adds the .rev, it has to check if the file exists and  
then display a dialog of it's own. This gives an inconsistent  
interface to the user and is generally bad GUI practice.

I was wondering if there is a way to get the ask file dialog to  
append the file extension, that why the check for the file being  
replaced would be handled just once and would therefore give  
consistent results.

All the Best
