How to use xcopy to only copy files if they are newer?

I have many web applications in a Visual Studio solution.

All have the same post build command:

xcopy "$(TargetDir)*.dll" "D:\Project\bin" /i /d /y

It would be useful to avoid replacing newer files with old ones (e.g. someone could accidentally add a reference to an old version of a DLL).

How can I use xcopy to replace old files only with newer DLL files generated by Visual Studio?

User following command to copy all new and modified file from source to destination

xcopy c:\source d:\destination /D /I /E /Y

/D to check any modified file are there
/I If the destination does not exist and copying more than one file, assumes that destination must be a directory.
/E To copy directory and sub directories
/Y to suppress any over write prompt.
