我目前正在使用shutil.copy2()来复制大量的图像文件和文件夹(0.5到5演出之间的任何地方). Shutil工作正常,但速度很慢.我想知道是否有办法将此信息传递给
Windows来制作副本并给我标准传输对话框.你知道,这家伙……
很多时候,我的脚本将花费大约两倍的标准Windows副本所花费的时间,并且让我感到紧张的是我的python解释器在运行副本时挂起.我多次运行复制过程,我希望减少时间.
如果你的目标是一个花哨的复制对话框,SHFileOperation Windows API函数提供了.
pywin32包有一个python绑定,ctypes也是一个选项(例如google“SHFileOperation ctypes”).

这是我使用pywin32的(非常轻微测试的)示例：
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
如果将上面的标志设置为shellcon.FOF_SILENT,您也可以在“静默模式”(无对话框,无确认,没有错误弹出窗口)中执行相同的复制操作. shellcon.FOF_NOCONFIRMATION | shellcon.FOF_NOERRORUI | shellcon.FOF_NOCONFIRMMKDIR.详情请见SHFILEOPSTRUCT.
