I have a directory, 'Dst Directory', which has files and folders in it and I have 'src Directory' which also has files and folders in it. What I want to do is move the contents of 'src Directory' to 'Dst Directory' and overwrite anyfiles that exist with the same name. So for example 'Src Directory\file.txt' needs to be moved to 'Dst Directory\' and overwrite the existing file.txt. The same applies for some folders, moving a folder and merging the contents with the same folder in 'dst directory'
I'm currently using shutil.move to move the contents of src to dst but it won't do it if the files already exist and it won't merge folders; it'll just put the folder inside the existing folder.
Update: To make things a bit clearer; What I'm doing is unzipping an archive to the Dst Directory and then moving the contents of Src Directory there and rezipping, effectively updating files in the zip archive. This will be repeated for adding new files or new versions of files etc which is why it needs to overwrite and merge
Solved: I solved my problem by using distutils.dir_util.copy_tree(src, dst), this copies the folders and files from src directory to dst directory and overwrites/merges where neccesary. Hope that helps some people!
Hope that makes sense, thanks!
copy() instead, which is willing to overwrite destination files. If you then want the first tree to go away, just
rmtree() it separately once you are done iterating over it.
os.walk() over the source tree. For each directory, check if it exists on the destination side, and
os.makedirs() it if it is missing. For each file, simply
shutil.copy() and the file will be created or overwritten, whichever is appropriate.
This will go through the source directory, create any directories that do not already exist in destination directory, and move files from source to the destination directory:
import os import shutil root_src_dir = 'Src Directory\\' root_dst_dir = 'Dst Directory\\' for src_dir, dirs, files in os.walk(root_src_dir): dst_dir = src_dir.replace(root_src_dir, root_dst_dir, 1) if not os.path.exists(dst_dir): os.makedirs(dst_dir) for file_ in files: src_file = os.path.join(src_dir, file_) dst_file = os.path.join(dst_dir, file_) if os.path.exists(dst_file): # in case of the src and dst are the same file if os.path.samefile(src_file, dst_file): continue os.remove(dst_file) shutil.move(src_file, dst_dir)
Any pre-existing files will be removed first (via
os.remove) before being replace by the corresponding source file. Any files or directories that already exist in the destination but not in the source will remain untouched.
