[Pharo-project] StandardFileStream>>forceNewFileNamed: open request window

Hi, I used the method StandardFileStream>>forceNewFileNamed: to create a new file but a window opens all the time telling me that the file doesn't exist and asking what I want to do about it. Is there another way I should use to create a file, and eventually overwrite it if it exists already, without having the system asking me what to do? Thanks, Fabrizio
