Google Drive Management

Comprehensive Google Drive integration enabling search, file operations, folder management, permissions control, and content synchronization through the Google Drive API v3.

Quick Start

When asked to work with Google Drive:

1. Authenticate: Set up OAuth2 credentials (one-time setup)
2. Search files: Find files by name, type, or content
3. Read content: Download and read file contents
4. Create/Update: Upload new files or modify existing ones
5. Organize: Create folders and move files
6. Share: Manage permissions and sharing

Prerequisites

One-Time Setup

1. Enable Google Drive API:

# Visit Google Cloud Console
# https://console.cloud.google.com/

# Enable Drive API for your project
# APIs & Services > Enable APIs and Services > Google Drive API

2. Create OAuth2 Credentials:

# In Google Cloud Console:
# APIs & Services > Credentials > Create Credentials > OAuth client ID
# Application type: Desktop app
# Download credentials as credentials.json

3. Install Dependencies:

pip install google-auth google-auth-oauthlib google-auth-httplib2 google-api-python-client --break-system-packages

4. Initial Authentication:

python scripts/authenticate.py
# Opens browser for Google sign-in
# Saves token.json for future use

See reference/setup-guide.md for detailed setup instructions.

Core Operations

Search for Files

Basic search:

python scripts/search_files.py --query "name contains 'report'"

Search patterns:

# By name
query = "name contains 'Q4 Report'"

# By type
query = "mimeType = 'application/vnd.google-apps.spreadsheet'"

# By folder
query = "'FOLDER_ID' in parents"

# Modified recently
query = "modifiedTime > '2025-01-01T00:00:00'"

# Combination
query = "name contains 'budget' and mimeType contains 'spreadsheet'"

Common searches:

# Find all PDFs
python scripts/search_files.py --type pdf

# Find files modified today
python scripts/search_files.py --modified-today

# Find files in specific folder
python scripts/search_files.py --folder "Project Documents"

# Search file content (for Google Docs/Sheets)
python scripts/search_files.py --content "quarterly review"

See reference/search-patterns.md for comprehensive query syntax.

Read File Content

# Binary files (PDFs, images, etc.)
python scripts/download_file.py --file-id FILE_ID --output ./local-file.pdf

Read Google Docs as text:

# Export as plain text
python scripts/read_doc.py --file-id FILE_ID

# Export as markdown
python scripts/read_doc.py --file-id FILE_ID --format markdown

Read Sheets data:

# Get sheet as CSV
python scripts/read_sheet.py --file-id FILE_ID --sheet "Sheet1"

API Rate Limits

Drive API quotas:

• Queries per day: 1,000,000,000
• Queries per 100 seconds per user: 1,000
• Queries per 100 seconds: 10,000

Best practices:

• Use batch requests for multiple operations
• Implement exponential backoff for rate limit errors
• Cache file IDs and metadata when possible
• Use partial responses to reduce data transfer

Error Handling

Common errors:

# 401 - Authentication failed
# Solution: Re-run authentication, check token.json

# 403 - Insufficient permissions
# Solution: Check OAuth scopes, request additional permissions

# 404 - File not found
# Solution: Verify file ID, check if file was deleted

# 429 - Rate limit exceeded
# Solution: Implement exponential backoff, reduce request frequency

# 500 - Backend error
# Solution: Retry with exponential backoff

Retry logic:

import time
from googleapiclient.errors import HttpError

def retry_request(request, max_retries=3):
    for attempt in range(max_retries):
        try:
            return request.execute()
        except HttpError as e:
            if e.resp.status in [429, 500, 503]:
                wait = (2 ** attempt) + random.random()
                time.sleep(wait)
            else:
                raise
    raise Exception("Max retries exceeded")

Security Best Practices

1. Never commit credentials:

   # Add to .gitignore
   credentials.json
   token.json
   client_secret*.json
   

2. Use minimal scopes:

   # Only request needed permissions
   SCOPES = ['https://www.googleapis.com/auth/drive.readonly']
   

3. Secure token storage:

   # Set proper permissions
   chmod 600 token.json
   

4. Rotate credentials regularly:

   # Delete old token to force re-authentication
   rm token.json
   python scripts/authenticate.py
   

OAuth Scopes

Available scopes:

# Full access
'https://www.googleapis.com/auth/drive'

# Read-only
'https://www.googleapis.com/auth/drive.readonly'

# File access (create/modify files created by app)
'https://www.googleapis.com/auth/drive.file'

# Metadata only
'https://www.googleapis.com/auth/drive.metadata.readonly'

# App data folder
'https://www.googleapis.com/auth/drive.appdata'

# Specific types
'https://www.googleapis.com/auth/drive.photos.readonly'

Choose the most restrictive scope that meets your needs.

Best Practices

1. Search before upload: Check if file exists to avoid duplicates
2. Use folders: Organize files in logical folder structures
3. Set metadata: Add descriptions and properties for better searchability
4. Batch operations: Process multiple files in single API call when possible
5. Cache file IDs: Store IDs locally to avoid repeated searches
6. Handle pagination: Use pageToken for large result sets
7. Export regularly: Backup important documents locally
8. Monitor quotas: Track API usage to stay within limits

Integration Examples

See examples/ for complete workflows:

• examples/project-sync.md - Project folder synchronization
• examples/document-workflow.md - Document creation and collaboration
• examples/data-processing.md - Sheets data processing
• examples/backup-strategy.md - Comprehensive backup approach

Troubleshooting

"Token has been expired or revoked"

rm token.json
python scripts/authenticate.py

"Insufficient permissions"

• Check SCOPES in scripts/authenticate.py
• May need to request additional permissions
• Delete token.json and re-authenticate with new scopes

"File not found"

• File may be in trash
• Check if you have access
• Verify file ID is correct

"Rate limit exceeded"

• Implement delays between requests
• Use batch operations
• Check your quota usage in Google Cloud Console
