Copy file and preserve all timestamps?


Recommended Posts

FileCopy() preserves only lastmodifed timestamp. creationdate and lastaccessed timestamps are set at the moment of copy the file.

NTFS timestamp accuracy is in microseconds, but AutoIt can get it in milliseconds and set in seconds, making FileGetTime() and FileSetTime() not accurate enough.

How can I create an identical copy of a file with identical timestamps?


Test code:

#include <WinAPIFiles.au3>
Local $sNow = @YEAR & @MON & @MDAY & @HOUR & @MIN & @SEC & @MSEC
$sFile = @TempDir & "\test" & $sNow & ".txt"
$sFile2 = $sFile & ".copy.txt"
FileWrite($sFile, $sNow)
FileCopy($sFile, $sFile2)
FileSetTime($sFile2, FileGetTime($sFile, $FT_CREATED, 3), $FT_CREATED)
ConsoleWrite("orig FileGetTime: " & FileGetTime($sFile, $FT_CREATED, 3) & @CRLF)
ConsoleWrite("orig wmic       : " & getTime($sFile) & @CRLF)
ConsoleWrite("copy FileGetTime: " & FileGetTime($sFile2, $FT_CREATED, 3) & @CRLF)
ConsoleWrite("copy wmic       : " & getTime($sFile2) & @CRLF)

Func getTime($sFile)
    Local $iPid = Run('wmic datafile where name="' & StringReplace($sFile, "\", "\\") & '" get creationdate', "", @SW_HIDE, 2)
    Local $sOut ;
        $sOut &= StdoutRead($iPid)
    Until @error
    Return StringRegExpReplace($sOut, "[^\d.-]", "")
EndFunc   ;==>getTime
