Nice! Thanks.

I guess the fsutil hardlink list command would work on Windows 7. It did work on the Windows 8 consumer preview I had.

Windows 7?

Yes

OK.

Not understanding the significance of this thread I asked my XP tower to look in my NTFS files & folders for WinSxS --- it produced same spread across 78 folders holding 341 files totalling 66MB. Should I feel deprived?

WinSxS is more of a "problem" with Windows Vista and above. I say "problem" in quotation because usually it goes astronomically large when the user has done something foolish like got a virus or installed some software which has broken things.

Brand new machine out the box and it's 7.5gb. Interesting. Doesn't really bother me though as long as it's not 50gb +
