Can I create folders I have a Samsung Galaxy s6 with Nougat.

When I connect,with cable,my phone to the pc in the window I can see "folders",on 

the phone I can't (archive>documents).

How can I see or create folders on my phone?

Thank you
There are a number of file managers available on Google Play. Simply select your favorite and you will be able to see the folders on your phone, from your phone.
