Question

我有一个带有子文件夹的文件夹结构，其中包含相同名称的文件。我想复制文件，包括文件夹层次结构。例如：

path/to/folder/A

包含包含文件a的子文件夹b，c，backup.txt。我想将它们复制到另一个文件夹：

path/to/another/destination

在Windows 10中找不到类似的东西。我试图在Python中解决此问题。

运行下面的代码应将A下的整个结构复制到path/to/another/destination，这样destination将具有文件夹A（包括A）的副本，但仅包含那些子文件夹其中包含文件file。

该代码不执行任何操作。它既不会在destination中创建文件夹（'A'），也不会将文件从源复制到目标。似乎未执行以下命令：os.mkdir，os.makedirs和shutil.copy。我在目的地中看不到任何新文件夹。

from sys import argv, exit
from os.path import split, splitext, join, isdir, exists, normpath
from os import walk, makedirs, mkdir, sep
from shutil import copy

file = argv[1]
source = normpath(argv[2])
dest = normpath(argv[3])
main_fol = source.split(sep)[-1]

for p,_,f in walk(source):
    char_fol = join(*p.split(sep)[-2:])
    new_dest = join(dest, main_fol, char_fol)
    for e in f:
        if file in e:
            if not exists(new_dest):
                mkdir(new_dest)
            copy(join(p,e), new_dest)

编辑。

我在D:\source中有一个源文件夹，其中包含许多包含文件ElvUI.*的子文件夹。我评论了copy和if not exit ...并在代码中添加了print行：

            # ...
            print("Fom:", join(p,e))
            print("To:", new_dest)
            print("")

当我执行python脚本时：

python copy_files.py ElvUI D:\source D:\destination

我在下面得到了这个输出。因此它确实可以找到文件。
