Update: вдогонку (совсем забыл), по поводу жёстких ссылок (и точек повторной обработки в целом) уже давным-давно было сказано — How to locate and correct disk space problems on NTFS volumes:

… Other NTFS features that may cause file allocation confusion NTFS also supports hard links and reparse points that allow volume mount points and directory junctions to be created. These additional NTFS features may cause confusion when you try to determine how much space is being consumed on a physical volume. A hard link is a directory entry for a file regardless of where the actual file data exists on that volume. Every file can be considered to have at least one hard link. On NTFS volumes, each file can have multiple hard links, and therefore a single file can appear in many directories (or even in the same directory with different names). Because all of the links reference the same file, programs can open any of the links and modify the file. A file is deleted from the file system only after all links to it have been deleted. After you create a hard link, programs can use it like any other file name. Keep in mind that Windows Explorer and a command prompt will show all linked files as being the same size, even though they all share the same data and don't actually use that amount of disk space. Volume mount points and directory junctions allow an empty folder on an NTFS volume to point to the root or subfolder on another volume. Windows Explorer and a DIR /s command follow the reparse point, count any files and directories on the destination volume, and include them in the host volume's statistics. This may lead you to believe that more space is being used on the host volume than what is actually being used.
