To my surprise I cannot find out how to do this without firing up one more Finder Window and fiddling with resizing in order to show both source and target at the same time.
Is the Finder really that bad?
Do I need to tell you how easy this is in Microsoft Windows Explorer?
On top of this the files are even queued in Windows 8 when you are moving from to several folders
After some more experimenting I noticed that you can get a really long expanded tree in the right pane, where you actually can drag files, but still I think it is more convenient in MS Windows to drag between right pane and left pane.
