How to delete all mail folder in gmail

To delete all mail folders in Gmail, you can follow these steps:

Method 1: Using the Gmail Web Interface

  1. Log in to your Gmail account.
  2. Click on the gear icon () in the upper right corner of the page.
  3. Select "See all settings" from the dropdown menu.
  4. Scroll down to the "Filters and Blocked Addresses" section.
  5. Click on the "Create a new filter" button.
  6. In the "From" field, enter @gmail.com (without quotes).
  7. Click on the "Create filter" button.
  8. In the "Apply the label" dropdown menu, select "Delete it".
  9. Click on the "Create" button.

This will delete all emails in your Gmail account, including all folders.

Method 2: Using the Gmail API

If you have a large number of emails and want to delete all folders programmatically, you can use the Gmail API. You'll need to:

  1. Enable the Gmail API for your project in the Google Cloud Console.
  2. Create a service account and generate a private key file.
  3. Install the Google API Client Library for your programming language of choice.
  4. Use the Gmail API to delete all emails in your account. You can use the users.messages.list method to retrieve a list of all emails, and then use the users.messages.delete method to delete each email.

Here's an example of how you might do this in Python using the Google API Client Library:

import os
import json
from google.oauth2 import service_account
from googleapiclient.discovery import build

# Set up authentication
creds = service_account.Credentials.from_service_account_file(
    'path/to/private/key.json',
    scopes=['https://www.googleapis.com/auth/gmail.modify']
)

# Create the Gmail API client
service = build('gmail', 'v1', credentials=creds)

# Retrieve a list of all emails in the account
response = service.users().messages().list(userId='me').execute()
messages = response.get('messages', [])

# Delete each email
for message in messages:
    message_id = message['id']
    service.users().messages().delete(userId='me', id=message_id).execute()

Important: Before deleting all emails in your Gmail account, make sure you have backed up any important emails or data you want to keep. Deleting all emails will permanently remove them from your account and cannot be undone.
