C#/Windows: why LastWriteTime can be earlier than CreationTime

Posted by jpluimers on 2011/10/05

I was wondering about file times like these:

CreationTime....: 5-10-2011 10:00:13
LastAccessTime..: 5-10-2011 12:05:58
LastWriteTime...: 5-10-2011 10:00:10

I found the answer on stackoverflow.

If a file is copied to another file, the new file retains the LastWriteTime of the source but the CreationTime will be the time of the copy.

And indeed: the file had been copied from a local directory to a central network location.
