It's possible that is a hard link. The OS files in Windows 7 are hard linked
to files in the store, in an effort to save data storage space. Some of the
files have four pointers to the same data. The existence of hard links,
makes it harder to figure out how much storage space your OS is using (like
doing properties on individual folders and adding the numbers together).
To study hard links first seen in Windows 7, I used my trusty Linux LiveCD,
as the files have reference counts that are easier to see.

The other kinds of options are mentioned in here. Too many options...

If I was de-duping, and had the options of...
1) Delete the spare copy.
2) Use hard link.
3) Use symbolic link.
4) Use shortcut.
I'd choose (1) purely for the simplicity. As it stands now, I know
my document folders contain nothing but ordinary files, which means
I have reasonable assurance they can be moved or maintained without
thinking about it. I can move any folder in my document tree to
any other folder, without having to think about it. And I can also
use any copy utility I want, as copying ordinary files doesn't
require any intelligence on the part of the utility.
