Delete a folder with files that have long names in Windows

This is more of a trick.  Back in the day we had to use subst on the path to make it shorter to delete it.

So what this does is use robocopy, which does not have a problem with long name, and tell it to mirror a blank folder on top of the problematic folder.  Since the source folder is empty it removes all files and folders.

robocopy C:\temp\empy_dir E:\dir_with_long_names /MIR
