A save question in an app

No. You can't do that. Not even with Applescript. Currently, you'd need an external to do that.

Usually, I check whether the user deleted the file extension. If yes, then I add the file extension again and check to see if the file already exists. If the files exists, I show the user an error message and leave it with that. The user will have to try saving again and will hopefully have learned not to delete the file extension.

On Mac OS X, you don't really need file extensions. You could do with file type and creator.

Best regards,

Is there anyway that only Untitled can be hilited so that the user enters a name for the file but the .datatxt extension is automatically saved to the file name selected by the user?
