I'm having troubles finding and deleting empty folders with my Python script. I have some directories with files more or less like this:
A/
--B/
----a.txt
----b.pdf
--C/
----d.pdf
I'm trying to delete all files which aren't PDFs and after that delete all empty folders. I can delete the files that I want to, but then I can't get the empty directories. What I'm doing wrong?
os.chdir(path+"/"+name+"/Test Data/Checklists")
pprint("Current path: "+ os.getcwd())
for root, dirs, files in os.walk(path+"/"+name+"/Test Data/Checklists"):
for name in files:
if not(name.endswith(".pdf")):
os.remove(os.path.join(root, name))
pprint("Deletting empty folders..")
pprint("Current path: "+ os.getcwd())
for root, dirs, files in os.walk(path+"/"+name+"/Test Data/Checklists", topdown=False):
if not dirs and not files:
os.rmdir(root)
use insted the function
os.removedirs(path)
this will remove directories until the parent directory is not empty.
Ideally, you should remove the directories immediately after deleting the files, rather than doing two passes with os.walk
import sys
import os
for dir, subdirs, files in os.walk(sys.argv[1], topdown=False):
for name in files:
if not(name.endswith(".pdf")):
os.remove(os.path.join(dir, name))
# check whether the directory is now empty after deletions, and if so, remove it
if len(os.listdir(dir)) == 0:
os.rmdir(dir)
For empty folders deletion you can use this snippet. It can be combined with some files deletion, but as last run should be used as is.
import os
def drop_empty_folders(directory):
"""Verify that every empty folder removed in local storage."""
for dirpath, dirnames, filenames in os.walk(directory, topdown=False):
if not dirnames and not filenames:
os.rmdir(dirpath)
remove all empty folders
import os
folders = './A/' # directory
for folder in list(os.walk(folders)) :
if not os.listdir(folder[0]):
os.removedirs(folder[0])
