The Complete Overview of How to Copy Files Between Google Drives
Google Drive’s architecture treats each account as an isolated silo, requiring explicit actions to replicate files across drives. Unlike local storage, where a simple copy-paste suffices, Google enforces ownership checks, sharing permissions, and API rate limits. The most reliable methods—whether native or third-party—hinge on understanding these constraints. For example, Google’s "Add shortcut" feature creates pointers rather than copies, while the "Download & Re-upload" workaround risks version discrepancies. The choice of method depends on file volume, ownership needs, and whether metadata (like edit history or comments) must persist. The process varies significantly between personal and business accounts. A Google Workspace admin might use domain-wide delegation, while an individual user relies on manual sharing or API scripts. Even the terminology is ambiguous: "Copy," "Move," and "Share" serve distinct purposes, and misinterpreting them can lead to data loss. Below, we dissect the mechanics behind each approach, including the hidden costs of third-party tools and the limitations of Google’s native functions.Historical Background and Evolution
Google Drive’s file-sharing capabilities emerged in 2012 as a response to the growing demand for cloud collaboration, but the ability to **transfer files between accounts** lagged behind due to security concerns. Early versions forced users to download files locally and re-upload them—a cumbersome process prone to errors. The introduction of "Shared Drives" (formerly Team Drives) in 2017 partially addressed this by allowing multi-account access, but individual account transfers remained fragmented. In 2020, Google rolled out the "Google Drive for Desktop" app, which synced files locally and enabled cross-account drag-and-drop transfers, though this method still didn’t preserve metadata. Meanwhile, third-party developers filled the gap with tools like MultCloud or CloudMounter, leveraging Google’s API to automate transfers. These tools evolved to handle bulk operations and complex permissions, but their reliability depends on API access levels, which Google frequently updates. Understanding this evolution is key to avoiding deprecated methods—such as using "Google Takeout" for transfers, which is now discouraged for large datasets.Core Mechanisms: How It Works
At its core, **copying files from one Google Drive to another** involves one of three technical pathways: direct API calls, intermediate storage (like local drives or third-party servers), or Google’s native sharing system. The API method, used by tools like Google Apps Script, bypasses the UI by authenticating with OAuth 2.0 and executing `files.copy()` commands. This preserves metadata but requires coding knowledge. Intermediate storage methods (e.g., downloading to a PC then re-uploading) are simpler but risk version conflicts if files are edited during transfer. Google’s native "Share" function, while user-friendly, only works for files the user owns and doesn’t replicate ownership—recipients gain access but can’t edit unless explicitly permitted. For shared drives, admins must use the "Transfer ownership" feature in Google Workspace, which triggers a domain-wide sync. Each method has trade-offs: API scripts offer control but demand technical skill, while native tools prioritize ease over customization. Below, we explore these trade-offs in detail.Key Benefits and Crucial Impact
Efficiently transferring files between Google Drives isn’t just about convenience—it’s a necessity for compliance, collaboration, and data integrity. Businesses migrating to Google Workspace avoid downtime by pre-loading files into new accounts, while individuals consolidating personal drives prevent storage fragmentation. The impact extends to version control: native methods like "Copy to Drive" create independent versions, whereas third-party tools may merge histories, complicating audits. For teams, the ability to **copy files from one Google Drive to another** while retaining permissions streamlines workflows. For example, a marketing agency can transfer campaign assets to a client’s drive without losing edit access. The benefits are clear, but the execution requires awareness of hidden pitfalls—such as Google’s 750GB file-size limit for API transfers or the 200-item batch limit in the Drive UI."Google Drive’s file transfer limitations reflect its design philosophy: prioritize security over convenience. Users must accept trade-offs—speed for simplicity, or control for complexity." — Google Workspace API Documentation Team
Major Advantages
- Preservation of Metadata: API-based methods or third-party tools like MultCloud retain file properties (e.g., creation dates, comments) that native "Share" functions omit.
- Bulk Transfer Capability: Tools like CloudMounter handle thousands of files via scheduled scripts, whereas manual methods cap at 200 items per batch.
- Ownership Control: Google Workspace admins can use "Transfer Ownership" to migrate files while maintaining domain policies, unlike personal accounts.

Future Trends and Innovations
Google’s push toward AI-driven automation suggests upcoming tools that could simplify **how to copy files from one Google Drive to another**—such as generative scripts that auto-map permissions or real-time sync for shared drives. The company’s focus on "Google AI" may integrate transfer logic into Drive’s UI, reducing reliance on third-party apps. However, security constraints will likely persist, as Google prioritizes audit trails over frictionless transfers. For users, the trend is toward hybrid methods: combining native tools for small transfers with API scripts for large-scale migrations. Expect more granular control over ownership rights and cross-service integrations (e.g., auto-copying from Google Photos to Drive). The key innovation will be balancing automation with data governance—ensuring transfers comply with GDPR or enterprise policies.
Conclusion

Q: Can I copy files from one Google Drive to another without losing ownership?
A: Yes, but only if you use Google Workspace’s "Transfer Ownership" feature (for admins) or a third-party tool like MultCloud that supports ownership replication. Native "Copy to Drive" creates a new owner (you), while "Share" only grants access.
Q: Why does Google limit the number of files I can copy at once?
A: Google’s UI enforces a 200-item batch limit to prevent server overload. For larger transfers, use Google Apps Script or a tool like CloudMounter, which bypasses this restriction via API.
Q: Will copying files to another Drive preserve comments or edit history?
A: Only API-based methods or third-party tools preserve metadata. Native "Copy to Drive" creates a static copy, while "Share" strips all history. For shared drives, use Google Workspace’s "Versioning" feature to retain logs.
Q: Can I automate transfers between Google Drives?
A: Yes, using Google Apps Script with triggers (e.g., "OnFileUpload") or third-party schedulers like Zapier. Example: A script can auto-copy new files from Drive A to Drive B daily.
Q: What’s the fastest way to transfer large files (e.g., 10GB+)?
A: Use Google’s "Download as ZIP" for files under 50GB, or a tool like Rclone for direct cloud-to-cloud transfers. Avoid email attachments or local downloads, which slow performance.
Q: Do I need a Google Workspace subscription to copy files between Drives?
A: No, but Workspace offers advanced features like domain-wide delegation. Personal accounts rely on manual methods or third-party tools, which may have usage limits.
Q: How do I handle permission errors when copying files?
A: If you’re the owner, use "Copy to Drive" to bypass sharing restrictions. For shared files, request edit access from the original owner or use a tool like SharePoint Migration Tool (for Workspace users).
Q: Can I copy files from Google Drive to another user’s Drive without them accepting a share?
A: No. Google requires recipient approval for shared files unless you’re the owner (then use "Copy to Drive") or an admin (then use "Transfer Ownership").
Q: What’s the difference between "Copy" and "Move" in Google Drive?
