See the Remarks section of https://msdn.microsoft.com/en-us/library/windows/desktop/aa363858%28v=vs.85%29.aspx Oh and, you have to use the FILE_FLAG_OPEN_REPARSE_POINT flag, of course. This might be the difference to Explorer. If the server accidentally returns the FILE_ATTRIBUTE_REPARSE_POINT flag only if the dir has been opened with FILE_FLAG_OPEN_REPARSE_POINT, Explorer would never see this. In contrast to Cygwin it's not interested in the fact whether the dir is a reparse point or not.
