Create directories before save

[user_deleted]

Hi

I'm writing a save tool running from a node python script button, i have my path set out to save and 

nuke.scriptSaveAs(path)

what i need now is for thius button to check directories and create paths before it saves so it creates the user folder -  i can find plenty of info on create directories before write but none on before save can anyone help me?

thanks

Marc
