New Folder

On the Actions menu, the New Folder command lets you create a folder at the current position.  If you have a file or folder selected, the new folder will be created with the same parent folder as the selected item.

If both sides are selected, a new folder will be created on both sides.

To create a new folder to use as a base folder, type the path for the new folder into the left or right edit controls, and press ENTER.  In the warning dialog that appears, click Create.
