how to create new folder for sub directory when saving blender file

Hi All,
Thanks for looking in. I want to know how to create a sub folder within a folder when saving a file on a drive. Where is the New Folder tab, icon, menu ?
Thanks
(see pic if unclear please)


Create new directory…:wink:


Too funny! That is why I do not snake hunt.

New Directory… Bloody Hell. I say, it must be an English thing. We call em’ new folders on this side of the pond.
