differences of disk usage between du and quota binaries

[Nicolas Letellier]

Hello.

I use FreeBSD 6.3. I set quota to my fs.
But, when I print disk usage with du -sh, I have:

root at domain sites $  du -sh folder
633M    folder

But, when I print disk usage with quota -u user, I have:

isk quotas for user user (uid 2002):
     Filesystem   usage   quota   limit   grace   files   quota   limit   grace
           /var  648264  700000  700000            2963       0       0


Why this difference? (633M against 648264)

Regards,
