It should be possible from the right click menu like in every other OS, but for some reason it's not. Same for creating directories.

To create new folder, right click in the window (not on a file nor a folder).

Copy paste also works with right click. To move (a la cut), hold option key.

Also hold option key to see "move" menu option under Edit - Paste (Move)
