python - 如何从 ctypes 使用 IFileOperation

Question

我想用IFileOperation从 python 代码复制文件 -

它很快(比 python 快)

你会得到一个很好的对话

不阻塞 Python

在 Windows 10 上，Python 3.8 -

import ctypes

ctypes.windll.shell32.IFileOperation

似乎不存在。

我如何联系 IFileOperation (不是已弃用的 SHFileOperation API)使用 ctypes ?

Answer 1

当然，它位于 pythoncom和 shell对于常量，例如:

from win32com.shell import shell
import pythoncom

# create an instance of IFileOperation
fo = pythoncom.CoCreateInstance(shell.CLSID_FileOperation, None, pythoncom.CLSCTX_ALL, shell.IID_IFileOperation)

# here you can use SetOperationFlags, progress Sinks, etc.

# create an instance of IShellItem for the source item
item1 = shell.SHCreateItemFromParsingName("c:\\temp\\source.txt", None, shell.IID_IShellItem)

# create an instance of IShellItem for the target folder
folder = shell.SHCreateItemFromParsingName("c:\\another", None, shell.IID_IShellItem)

# queue the copy operation
fo.CopyItem(item1, folder, "new name.txt", None)

# commit
fo.PerformOperations()
