当我试图删除一个非空文件夹时,我得到一个“访问被拒绝”错误。我在尝试中使用了以下命令:os.remove("/folder_name")。
删除一个非空文件夹/目录最有效的方法是什么?

当前回答
在python 3.4中,你可以使用:
import pathlib
def delete_folder(pth) :
for sub in pth.iterdir() :
if sub.is_dir() :
delete_folder(sub)
else :
sub.unlink()
pth.rmdir() # if you just want to delete the dir content but not the dir itself, remove this line
其中PTH是一个pathlib。路径实例。不错,但可能不是最快的。
其他回答
对于Windows,如果目录不是空的,并且你有只读文件或者你会得到这样的错误
访问被拒绝 该进程无法访问该文件,因为它正被另一个进程使用
试试这个,os。system('rmdir /S /Q "{}"'.format(directory))
它相当于Linux/Mac中的rm -rf。
您可以尝试下面的代码删除文件或文件夹,而不管它们是空的还是非空的。
import shutil
import os
directory = "path/to/the/root/folder"
files_in_directory = os.listdir(directory)
for file in files_in_directory:
try:
path_to_file_or_folder = os.path.join(directory, file)
shutil.rmtree(path_to_file_or_folder)
except:
os.unlink(path_to_file_or_folder)
只需一些python 3.5选项就可以完成上面的回答。(我很想在这里找到它们)。
import os
import shutil
from send2trash import send2trash # (shutil delete permanently)
删除空文件夹
root = r"C:\Users\Me\Desktop\test"
for dir, subdirs, files in os.walk(root):
if subdirs == [] and files == []:
send2trash(dir)
print(dir, ": folder removed")
删除包含此文件的also文件夹
elif subdirs == [] and len(files) == 1: # if contains no sub folder and only 1 file
if files[0]== "desktop.ini" or:
send2trash(dir)
print(dir, ": folder removed")
else:
print(dir)
删除只包含.srt或.txt文件的文件夹
elif subdirs == []: #if dir doesn’t contains subdirectory
ext = (".srt", ".txt")
contains_other_ext=0
for file in files:
if not file.endswith(ext):
contains_other_ext=True
if contains_other_ext== 0:
send2trash(dir)
print(dir, ": dir deleted")
删除小于400kb的文件夹:
def get_tree_size(path):
"""Return total size of files in given path and subdirs."""
total = 0
for entry in os.scandir(path):
if entry.is_dir(follow_symlinks=False):
total += get_tree_size(entry.path)
else:
total += entry.stat(follow_symlinks=False).st_size
return total
for dir, subdirs, files in os.walk(root):
If get_tree_size(dir) < 400000: # ≈ 400kb
send2trash(dir)
print(dir, "dir deleted")
在我的情况下,删除的唯一方法是使用所有的可能性,因为我的代码应该运行cmd.exe或powershell.exe。如果是你的情况,只需要用下面的代码创建一个函数就可以了:
#!/usr/bin/env python3
import shutil
from os import path, system
import sys
# Try to delete the folder ---------------------------------------------
if (path.isdir(folder)):
shutil.rmtree(folder, ignore_errors=True)
if (path.isdir(folder)):
try:
system("rd -r {0}".format(folder))
except Exception as e:
print("WARN: Failed to delete => {0}".format(e),file=sys.stderr)
if (path.isdir(self.backup_folder_wrk)):
try:
system("rd /s /q {0}".format(folder))
except Exception as e:
print("WARN: Failed to delete => {0}".format(e),file=sys.stderr)
if (path.isdir(folder)):
print("WARN: Failed to delete {0}".format(folder),file=sys.stderr)
# -------------------------------------------------------------------------------------
删除一个文件夹,即使它可能不存在(避免Charles Chow回答中的竞态条件),但当其他事情出错时仍然有错误(例如权限问题,磁盘读取错误,文件不是目录)
对于Python 3.x:
import shutil
def ignore_absent_file(func, path, exc_inf):
except_instance = exc_inf[1]
if isinstance(except_instance, FileNotFoundError):
return
raise except_instance
shutil.rmtree(dir_to_delete, onerror=ignore_absent_file)
Python 2.7的代码几乎是一样的:
import shutil
import errno
def ignore_absent_file(func, path, exc_inf):
except_instance = exc_inf[1]
if isinstance(except_instance, OSError) and \
except_instance.errno == errno.ENOENT:
return
raise except_instance
shutil.rmtree(dir_to_delete, onerror=ignore_absent_file)
