To create a folder in Box you will need to provide our API with a name for the
new folder, as well as the id of the parent folder that you would like to
create the new folder within.
There are some restrictions to the folder name. Names containing non-printable
ASCII characters, forward and backward slashes (/, \), as well as names
with trailing spaces are prohibited.
Additionally, the names . and .. are reserved names and therefore
also prohibited.
