CreateFile() create time
in [Win32 API]

From: Kevin English on 27 Jul 2010 21:29 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. -- Kevin English

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. -- Kevin English
