In SharePoint 2010, the easiest way to transfer documents from one library to another
involved using two Explorer Views and dragging and dropping. While this process works,
it is incredibly inefficient and slow. The files must literally first be transferred to the user’s
workstation from the server, then moved back the server and onto the final destination
library.
You can now select single or multiple files and drag them into a folder, or document set,
located in the same library, all within the browser. You no longer have to open up sepa -
rate Explorer Views; the move is handled at the server level. Additionally, you can drop a
single document, or several documents, right from the library into another library by simply
selecting files and dragging them over the target document library on the Quick Launch bar.
There are some limitations, however. The primary limitation is that you cannot drag files
directly into folders on a second level or lower. You will need to drag and drop the file into
the first-level folder and repeat the same action with the next-level folder until you have
reached the folder you are targeting as the destination. You cannot drag and drop between
site collections. This is true even if the same account is granted rights to the separate site
collections. You cannot move individual videos or list items in any fashion. Finally, you
cannot move entire folders or document sets from one location to another location.

例如：选取多个文件拖拽到另外文档库，即可实现文件的移动。

当用鼠标拖拽文档时，遇到相同文档名会有一下提示：
