DEDUPE suggestion:
Add switches:
/H Convert duplicate files to hardlinks to the first file. Note that to create hardlinks, you do NOT need to be in an elevated session. Also note, that hardlinks ONLY works when the files are located on the same physical device. If you want to use symlinks when hardlinks aren't possible, also add /L switch (/H switch takes precedence).
/K Keep the file's time stamp when replacing it with a symlink/hardlink
