Comment:

 Looks like this was addressed with the changes for #3300.

 libraries/directory:

  {{{

    * Windows: Unicode getDirectoryContents and setPermissions
  }}}

 Both 7.0 and 7.1 work for me:

 {{{
 > getDirectoryContents "C:\\System Volume Information\\"
 *** Exception: C:\System Volume Information\: getDirectoryContents:
 permission denied (Access is denied.)
 }}}
