使用Windows複製對話框複製

Question

我目前使用shutil.copy2()來複制大量的圖像文件和文件夾（任何地方在0.5到5個演出之間）。 Shutil工作正常，但速度很慢。我想知道是否有辦法將這些信息傳遞給Windows來製作副本並給我它的標準傳輸對話框。要知道，這傢伙......

很多時候，我的腳本將需要大約兩倍的標準的windows複製所需的時間，這讓我很緊張，我的Python解釋器在運行復制掛起。我多次運行復制過程，並且期望縮短時間。

Answer 1

請參閱IFileCopy。 IFileOperation 可能可通過ctypes和shell32.dll，我不知道。

Answer 2

如果你的目標是一個奇特的複製對話框，SHFileOperation Windows API函數提供。 pywin32包有一個Python綁定它，ctypes也是一個選項（谷歌「SHFileOperation ctypes」的例子）。

這裏使用pywin32我（看得很輕測試）例如：

import os.path 
from win32com.shell import shell, shellcon 


def win32_shellcopy(src, dest): 
    """ 
    Copy files and directories using Windows shell. 

    :param src: Path or a list of paths to copy. Filename portion of a path 
       (but not directory portion) can contain wildcards ``*`` and 
       ``?``. 
    :param dst: destination directory. 
    :returns: ``True`` if the operation completed successfully, 
       ``False`` if it was aborted by user (completed partially). 
    :raises: ``WindowsError`` if anything went wrong. Typically, when source 
      file was not found. 

    .. seealso: 
     `SHFileperation on MSDN <http://msdn.microsoft.com/en-us/library/windows/desktop/bb762164(v=vs.85).aspx>` 
    """ 
    if isinstance(src, basestring): # in Py3 replace basestring with str 
     src = os.path.abspath(src) 
    else: # iterable 
     src = '\0'.join(os.path.abspath(path) for path in src) 

    result, aborted = shell.SHFileOperation((
     0, 
     shellcon.FO_COPY, 
     src, 
     os.path.abspath(dest), 
     shellcon.FOF_NOCONFIRMMKDIR, # flags 
     None, 
     None)) 

    if not aborted and result != 0: 
     # Note: raising a WindowsError with correct error code is quite 
     # difficult due to SHFileOperation historical idiosyncrasies. 
     # Therefore we simply pass a message. 
     raise WindowsError('SHFileOperation failed: 0x%08x' % result) 

    return not aborted 

您還可以在「靜音模式」（無對話，無confirmationsm，沒有錯誤彈出窗口），如果你設置執行相同的複製操作上面的標誌爲shellcon.FOF_SILENT | shellcon.FOF_NOCONFIRMATION | shellcon.FOF_NOERRORUI | shellcon.FOF_NOCONFIRMMKDIR.詳見SHFILEOPSTRUCT。

將是很好，有它包裹在一個圖書館......隨着答案的幫助上面，我是能夠得到它在Windows 7上工作如下。這裏

import pythoncom 
from win32com.shell import shell,shellcon 

def win_copy_files(src_files,dst_folder):   
     # @see IFileOperation 
     pfo = pythoncom.CoCreateInstance(shell.CLSID_FileOperation,None,pythoncom.CLSCTX_ALL,shell.IID_IFileOperation) 

     # Respond with Yes to All for any dialog 
     # @see http://msdn.microsoft.com/en-us/library/bb775799(v=vs.85).aspx 
     pfo.SetOperationFlags(shellcon.FOF_NOCONFIRMATION) 

     # Set the destionation folder 
     dst = shell.SHCreateItemFromParsingName(dst_folder,None,shell.IID_IShellItem) 

     for f in src_files: 
       src = shell.SHCreateItemFromParsingName(f,None,shell.IID_IShellItem) 
       pfo.CopyItem(src,dst) # Schedule an operation to be performed 


     # @see http://msdn.microsoft.com/en-us/library/bb775780(v=vs.85).aspx 
     success = pfo.PerformOperations() 

     # @see sdn.microsoft.com/en-us/library/bb775769(v=vs.85).aspx 
     aborted = pfo.GetAnyOperationsAborted() 
     return success and not aborted 


files_to_copy = [r'C:\Users\jrm\Documents\test1.txt',r'C:\Users\jrm\Documents\test2.txt'] 
dest_folder = r'C:\Users\jrm\Documents\dst' 
win_copy_files(files_to_copy,dest_folder)
