How do I move files in the Share Documents section Sharepoint?

I'm doing some reorganization in a Shared Documents section of one of our Sharepoint sites.

One of the current folders is setup like this:

Documents -> Documents -> OnBase

What I'd like to do is either:

A) Move the Onbase Folder up to the same level as the root Documents folder

OR

B) Move all the files within the OnBase folder into the root Documents folder so I can simply rename it.

All my initial digging around Sharepoint is coming up with nothing.

How do I do this?
