I was working in a Document Library and the View was missing the New button to allow for folder creation.
Simple fix.
Site Actions > Edit Page > (the web part you want to fix) click edit > Modify Shared Web Part
In the Web Part properties window click on Edit the current view
Now scroll down to until you see Folders.
Select Show items inside folders in Folders or Flat:
Done.
Sharepointed indeed.
Random problme, simple fix written well.
Thanks
