Python: Copy directories, not files, from multiple locations, overwriting if same name

Question

I have a main folder netbooks_nbo which contain more dated folders. I want to get the last seven folders (by last modified date) and copy them to somewhere on the C:\\ drive. Here's my current code:

Code looks like this:

import os
import distutils.core

def get_immediate_subdirectories(dir):
    return [os.path.join(dir, name) for name in os.listdir(dir)
            if os.path.isdir(os.path.join(dir, name))]

def main():
    path = "\\\\Network_Drive\\netbooks_nbo"
    all_dirs = get_immediate_subdirectories(path)
    all_dirs.sort(key=lambda x: os.path.getmtime(x))
    all_dirs = all_dirs[len(all_dirs)-7: len(all_dirs)]

    for i in all_dirs:
        for n in get_immediate_subdirectories(i):
            distutils.dir_util.copy_tree(n, "C:\\AllFiles")
            print "copied"+ n

The problem is that dir_util.copy_tree copies all the files, rather than the actual directories. I want to preserve the directory structure. I tried using shutil.copytree(src, dst) but it just returns an Error because C:\\AllFiles will already exist after one iteration of the for loop. And shutil.copy(src,dst) doesn't work because of some bizarre permission error.

Any ideas?

如果目录树不是太大，则可以将每个目录树打包到一个存档文件中 ，然后将每个存档文件解压缩到目标位置。
