CreateFile() create time
Hi,
Can anyone explain the reasoning behind the fact that a successful
DeleteFile(<fn>) followed by a successful
CreateFile(<fn>...,CREATE_NEW..) sets the file creation time to the
old creation time rather than the current system time. I understand
that it is using a cached value, just not the reason why. I also
understand that I can set the file creation time to any time of my
choosing, but not sure why I should have to?
This behavior is confirmed on Windows XP NTFS file systems and I
expect it is consistent across all windows os's.
Thanks for any info.

Thanks. I guess under some some circumstances I would have been
equally puzzled why the creation time wasn't preserved. Also liked
the Quantum Mechanics analogy.
