File copying

In digital file management, copying is a file operation that creates a new file which has the same content as an existing file. Computer operating systems include file copying methods to users; operating systems with graphical user interfaces (GUIs) often providing copy-and-paste or drag-and-drop methods of file copying. Operating systems may have specialized file-copying APIs are usually able to tell the server to perform the copying locally, without sending file contents over the network, thus greatly improving performance.
