Accessing folders, subfolders and subfiles using PyDrive (Python)

Question

I have the following code from the PyDrive documentation that allows access to top level folders in my Google Drive. I would like to access all of the folders, subfolders, and files from it. How would I go about doing this (I just started using PyDrive)?

#!/usr/bin/python
# -*- coding: utf-8 -*-
from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive


gauth = GoogleAuth()
gauth.LocalWebserverAuth() # Creates local webserver and auto handles authentication

#Make GoogleDrive instance with Authenticated GoogleAuth instance
drive = GoogleDrive(gauth)

#Google_Drive_Tree = 
# Auto-iterate through all files that matches this query
top_list = drive.ListFile({'q': "'root' in parents and trashed=false"}).GetList()
for file in top_list:
    print 'title: %s, id: %s' % (file['title'], file['id'])
    print "---------------------------------------------"

#Paginate file lists by specifying number of max results
for file_list in drive.ListFile({'q': 'trashed=true', 'maxResults': 10}):
    print 'Received %s files from Files.list()' % len(file_list) # <= 10
    for file1 in file_list:
        print 'title: %s, id: %s' % (file1['title'], file1['id'])

I have checked the following page How to list all files, folders, subfolders and subfiles of a Google drive folder , which seemed to be the answer I was looking for but the code is not there anymore.

Answer 1

It requires iteration with list of files. Based on this, the code fetches the title of file and url link of the each files with in the folder. The code is adjustable to get the specific folder by supplying the id of the folder such as ListFolder('id'). The given below example is querying the root

#!/usr/bin/python
# -*- coding: utf-8 -*-
from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive

gauth = GoogleAuth()
gauth.LocalWebserverAuth() # Creates local webserver and auto handles authentication

#Make GoogleDrive instance with Authenticated GoogleAuth instance
drive = GoogleDrive(gauth)

def ListFolder(parent):
  filelist=[]
  file_list = drive.ListFile({'q': "'%s' in parents and trashed=false" % parent}).GetList()
  for f in file_list:
    if f['mimeType']=='application/vnd.google-apps.folder': # if folder
        filelist.append({"id":f['id'],"title":f['title'],"list":ListFolder(f['id'])})
    else:
        filelist.append({"title":f['title'],"title1":f['alternateLink']})
  return filelist

ListFolder('root')

Your code is absolutely correct. But with the default settings of Pydrive , you have access to only the root level files and folders. Changing oauth_scope in settings.yaml file fixes this issue.

client_config_backend: settings
client_config:
client_id: XXX
client_secret: XXXX

save_credentials: True
save_credentials_backend: file
save_credentials_file: credentials.json

get_refresh_token: True

oauth_scope:
  - https://www.googleapis.com/auth/drive
  - https://www.googleapis.com/auth/drive.metadata
