import pywintypes, win32file, win32con
def changeFileCreationTime(fname, newtime):
    wintime = pywintypes.Time(newtime)
    winfile = win32file.CreateFile(
        fname, win32con.GENERIC_WRITE,
        win32con.FILE_SHARE_READ | win32con.FILE_SHARE_WRITE | win32con.FILE_SHARE_DELETE,
        None, win32con.OPEN_EXISTING,
        win32con.FILE_ATTRIBUTE_NORMAL, None)

    win32file.SetFileTime(winfile, wintime, None, None)

    winfile.close()

Answer 2

installer l'extension pywin32 https://sourceforge.net/projects/pywin32/files/pywin32/Build%20221/

import win32file
import pywintypes

# main logic function
def changeFileCreateTime(path, ctime):
    # path: your file path
    # ctime: Unix timestamp

    # open file and get the handle of file
    # API: http://timgolden.me.uk/pywin32-docs/win32file__CreateFile_meth.html
    handle = win32file.CreateFile(
        path,                          # file path
        win32file.GENERIC_WRITE,       # must opened with GENERIC_WRITE access
        0,
        None,
        win32file.OPEN_EXISTING,
        0,
        0
    )

    # create a PyTime object
    # API: http://timgolden.me.uk/pywin32-docs/pywintypes__Time_meth.html
    PyTime = pywintypes.Time(ctime)

    # reset the create time of file
    # API: http://timgolden.me.uk/pywin32-docs/win32file__SetFileTime_meth.html
    win32file.SetFileTime(
        handle,
        PyTime
    )

# example
changeFileCreateTime('C:/Users/percy/Desktop/1.txt',1234567789)

Answer 3

import os
os.utime(path, (accessed_time, modified_time))

http://docs.python.org/library/os.html

Au moins, il modifie le temps de modification, sans utiliser le module win32.
