5 Ways to Copy a Shared Google Drive Folder (Complete Benchmark & Comparison)
Quick Summary: Google Drive natively prevents users from duplicating entire folders with one click. When someone shares a directory containing hundreds of files and nested subfolders, you cannot simply right-click and select "Make a copy". Below is an exhaustive technical comparison of the 5 primary methods used to duplicate shared Google Drive folders, analyzing bandwidth cost, execution limits, data privacy, and ease of use.
Technical Comparison Matrix
| Feature / Metric | 1. Manual ZIP Download | 2. Google Apps Script | 3. rclone CLI | 4. MultCloud / SaaS | 5. MyDrive Copier |
|---|---|---|---|---|---|
| Transfer Architecture | Client PC ↔ Google Cloud | Cloud ↔ Cloud (Apps Script) | Terminal ↔ Cloud (or VPS) | Third-Party Server Proxy | Browser-Orchestrated Cloud-to-Cloud |
| Local Bandwidth | 100% Download + Upload | 0% (Pure Cloud) | VPS or Local PC Dependent | 0% (Proxy Cloud) | 0% (Pure Cloud) |
| Preserves Folder Tree | Splits into multiple ZIPs | Script-dependent | Yes | Yes | Exact 1:1 Mirror |
| Native Google Docs | Converts to docx/xlsx | Requires custom MIME handling | Requires export flags | Varies | 100% Native Google Docs |
| Execution Limits | Browser network timeouts | Hard 6-Minute Timeout | None (CLI session) | Bandwidth caps on free tier | Persistent MV3 Worker |
| Rate Limits (403/429) | Manual retry | Fails on quota limits | Configurable flags | Server-managed | Automated Exponential Backoff |
| Data Privacy & Security | Stores files on local disk | Runs in user account | API key in rclone.conf | Third-party server stores tokens | Client-only OAuth, zero server storage |
| Setup Complexity | Low (but tedious) | High (Requires JS editing) | Very High (Terminal, GCP setup) | Medium (Account signup) | 1-Click (Chrome Extension) |
| Cost | Free | Free | Free | $9.90 - $19.90 / month | 50 Files Free, $12.99 Lifetime |
Detailed Analysis of Each Method
1. The Native Workaround: Manual ZIP Download & Re-Upload
Manual
How it works: In Google Drive, right-click the shared folder and select "Download". Google compresses the contents into an archive. Once downloaded, you extract the ZIP file locally on your disk, then drag and drop the folder into "My Drive".
Major Pitfalls:
- Archive Fragmentation: Folders exceeding 2GB are automatically sliced by Google into multiple partial archives (
drive-download-001.zip,drive-download-002.zip). Recombining them manually frequently scrambles subdirectory hierarchies. - Destruction of Native Google Docs: Google Docs, Sheets, and Slides are forcibly converted into Microsoft Word (.docx), Excel (.xlsx), and PowerPoint (.pptx). Comment threads, version history, and collaborative formatting are permanently severed.
- Massive Bandwidth Consumption: Duplicating a 25GB shared dataset burns 50GB of total network data (25GB down + 25GB up), stressing home connections.
2. Google Apps Script: Custom JavaScript Automation
Developer
How it works: Developers write serverless JavaScript code inside the Google Apps Script editor, utilizing DriveApp or the Google Drive Advanced API to recursively traverse folder IDs and copy files.
Major Pitfalls:
- The 6-Minute Hard Wall: Google enforces a strict 6-minute maximum execution time limit per run for standard Google accounts. Folders with more than 300–500 files hit
Exceeded maximum execution timeand crash mid-copy, leaving orphaned files and duplicate directories. - No Built-in Resume or State Management: Resuming an interrupted script requires complex token tracking stored in script properties, which is prone to failure and difficult for non-engineers to debug.
3. rclone: The Open-Source Command-Line Powerhouse
Sysadmin
How it works: rclone is a command-line synchronization program written in Go that interfaces directly with Google Drive API v3 via configured remotes.
Major Pitfalls:
- High Barrier to Entry: Requires creating a Google Cloud Project, configuring OAuth consent screens, generating client secrets, editing
rclone.confvia interactive terminal prompts, and configuring specific flags (--drive-server-side-copy). - Local Machine Dependency: Unless executed on a remote cloud VPS, rclone requires keeping your local terminal session open for the entire duration of the copy.
4. Third-Party Cloud SaaS (e.g. MultCloud)
Commercial SaaS
How it works: Third-party cloud migration platforms ask you to authorize access to your Google accounts, then perform file transfers across their private server clusters.
Major Pitfalls:
- Data Privacy & Token Risks: You must grant full read/write Google Drive OAuth tokens to third-party commercial servers, creating substantial privacy and regulatory compliance liabilities.
- Expensive Recurring Subscriptions: Most SaaS cloud duplicators charge $9.90 to $24.90 per month, or cap free users at 5GB of total lifetime transfer data.
5. MyDrive Copier: Native Browser-Orchestrated Duplicator
★ Recommended
How it works: Runs directly inside Google Chrome via a Manifest V3 background service worker. Orchestrates official Google Drive API v3 files.copy commands directly between Google's cloud servers without routing any file data through third parties.
Key Engineering Advantages:
- 100% Direct Cloud-to-Cloud: Zero bytes downloaded to your hard drive; zero local bandwidth consumed. Files copy server-side in Google's data centers.
- Automated Rate-Limit Engine: Automatically catches HTTP 403 (User Rate Limit Exceeded) and HTTP 429 (Too Many Requests) errors, dynamically throttling concurrency with randomized exponential jitter backoff.
- 100% Native Google Docs Preservation: Google Docs, Sheets, and Slides duplicate as native Google Docs with all formulas and formatting intact.
- Complete Data Privacy: Authentication tokens are stored exclusively inside Chrome's secure client-side storage. No middleman server ever accesses or stores your Google credentials or files.
- Dual Engine Architecture: Includes an instant built-in OAuth engine for casual users, plus an optional BYOK (Bring Your Own Key) mode for power users desiring dedicated, isolated API quota.
Which Method Should You Choose?
- Choose rclone if: You are a Linux systems administrator managing automated cron backup jobs across petabytes of enterprise storage on a dedicated VPS.
- Choose Google Apps Script if: You have fewer than 50 files and enjoy writing custom JavaScript logic inside Google Workspace.
- Choose MyDrive Copier if: You want a fast, zero-configuration solution directly in your browser that replicates deep nested folder hierarchies in 1 click without downloading files, hitting 6-minute timeouts, or paying monthly subscriptions.
