In Sharepoint 2010, I was able to upload entire folders, by choosing Upload Multiple Files and dragging and dropping the folder into the designated location. Or by selecting the folder at upload point.
However, in 2013, I am not able to find out how to do this in Sharepoint 2013.
Dragging and dropping a folder into a library gives the message:
Folders and invalid files can't be dragged to upload.
And I can't seem a select a folder in the browse window that opens up from the "Choose a file" textbox of "Add a document" window, either.
So how can I upload an entire folder into Sharepoint 2013 at one-go?
