How do I change the file creation date of a Window

问题:

How do I change the file creation date of a Windows file from Python?

回答1:

Yak shaving for the win.

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()

回答2:

This code works on python 3 without ValueError: astimezone() cannot be applied to a naive datetime:

wintime = datetime.datetime.utcfromtimestamp(newtime).replace(tzinfo=datetime.timezone.utc)
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)
winfile.close()

install pywin32 extension first 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)

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

Here's a more robust version of the accepted answer. It also has the opposing getter function. This addresses created, modified, and accessed datetimes. It handles having the datetimes parameters provided as either datetime.datetime objects, or as "seconds since the epoch" (what the getter returns). Further, it adjusts for Day Light Saving time, which the accepted answer does not. Without that, your times will not be set correctly when you set a winter or summer time during the opposing phase of your actual system time.

The major weakness of this answer is that it is for Windows only (which answers the question posed). In the future, I'll try to post a cross platform solution.

def isWindows() :
  import platform
  return platform.system() == 'Windows' 

def getFileDateTimes( filePath ):        
    return ( os.path.getctime( filePath ), 
             os.path.getmtime( filePath ), 
             os.path.getatime( filePath ) )

def setFileDateTimes( filePath, datetimes ):
    try :
        import datetime
        import time 
        if isWindows() :
            import win32file, win32con
            ctime = datetimes[0]
            mtime = datetimes[1]
            atime = datetimes[2]
            # handle datetime.datetime parameters
            if isinstance( ctime, datetime.datetime ) :
                ctime = time.mktime( ctime.timetuple() ) 
            if isinstance( mtime, datetime.datetime ) :
                mtime = time.mktime( mtime.timetuple() ) 
            if isinstance( atime, datetime.datetime ) :
                atime = time.mktime( atime.timetuple() )             
            # adjust for day light savings     
            now = time.localtime()
            ctime += 3600 * (now.tm_isdst - time.localtime(ctime).tm_isdst)
            mtime += 3600 * (now.tm_isdst - time.localtime(mtime).tm_isdst)
            atime += 3600 * (now.tm_isdst - time.localtime(atime).tm_isdst)            
            # change time stamps
            winfile = win32file.CreateFile(
                filePath, 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, ctime, atime, mtime )
            winfile.close()
        else : """MUST FIGURE OUT..."""
    except : pass

Here is a solution that works on Python 3.5 and windows 7. Very easy. I admit it's sloppy coding... but it works. You're welcome to clean it up. I just needed a quick soln.

import pywintypes, win32file, win32con, datetime, pytz

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,  wintime,     wintime)
    # None doesnt change args = file,     creation, last access, last write
    # win32file.SetFileTime(None, None, None, None) # does nonething
    winfile.close()

if __name__ == "__main__":
    local_tz = pytz.timezone('Antarctica/South_Pole')
    start_date = local_tz.localize(datetime.datetime(1776,7,4), is_dst=None)
    changeFileCreationTime(r'C:\homemade.pr0n', start_date )
