If you want to use Varun's ROBOCOPY command line in the Explorer context menu (i.e. right-click) here is a Windows registry import. I tried adding this as a comment to his answer, but the inline markup wasn't feasible.
I've tested this on my own Windows 10 PC, but use at your own risk. It will open a new command prompt, run the command, and pause so you can see the output.
Copy into a new text file:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Classes\directory\Background\shell\Delete Empty Folders\command] @="C:\Windows\System32\Cmd.exe /C \"C:\Windows\System32\Robocopy.exe \"%V\" \"%V\" /s /move\" && PAUSE"
[HKEY_CURRENT_USER\Software\Classes\directory\shell\Delete Empty Folders\command] @="C:\Windows\System32\Cmd.exe /C \"C:\Windows\System32\Robocopy.exe \"%V\" \"%V\" /s /move\" && PAUSE"
Rename the .txt extension to .reg
