You can use xcopy command for copy and move files. Below command does that it copy files and paste to new destination without overwrite existing files.
xcopy
C:\> xcopy D:\source_dest E:\target_dest /E /D
Note : /E parameter make that it copy files with subfolders
Note : /D parameter make that it copy files without overwrite
