iCloud Drive to Filen Transfer: 3 Ways to Move Your Apple Files to Encrypted Storage

Learn how to transfer files from iCloud Drive to Filen using three methods: browser download/upload, macOS Finder bridge, or cloud-to-cloud transfer with CloudsLinker. Migrate your Apple ecosystem files to zero-knowledge encrypted storage.

Introduction

Moving from iCloud Drive to Filen means shifting from Apple's integrated ecosystem to a privacy-first, zero-knowledge encrypted platform. Whether you're concerned about data privacy or just want your files outside the Apple walled garden, the migration is straightforward once you pick the right method. This guide covers three approaches: a quick browser move for small folders, a Finder-based sync for macOS users who want local control, and a cloud-to-cloud transfer with CloudsLinker for hands-off migration of larger libraries.

Start Cloud Transfer Compare Methods

Apple ecosystem note: iCloud Drive is tightly integrated with macOS and iOS. If your files are set to "Optimize Mac Storage," you'll need to download them locally first before any transfer method will work.

Pick a Method in 30 Seconds

Any platform

Browser Transfer

Works on any device. Best for small folders.

macOS users

Finder Bridge

Use iCloud Drive in Finder + Filen Desktop for local control.

Hands-off

Cloud-to-Cloud

Ideal for large libraries without local bandwidth limits.

Method 1: Download from iCloud.com, Upload to Filen (Browser)

Best for: small folders, cross-platform users, one-time transfers.
Trade-off: manual process, requires downloading to local storage first.

Step 1: Download files from iCloud.com

Open iCloud.com in your browser and sign in with your Apple ID. Navigate to iCloud Drive, select the files or folders you want to migrate, and click the download button.

iCloud will package selected items into a ZIP file. For large downloads, consider selecting smaller batches to avoid timeout issues.

Step 2: Extract and organize locally

Unzip the downloaded archive and verify the folder structure. This is a good time to rename folders or remove files you don't need in Filen.

Step 3: Upload to Filen

Open the Filen web app, navigate to your target folder, and upload the extracted files via drag-and-drop. Files are encrypted locally before upload.

Method 2: macOS Finder Bridge (iCloud Drive + Filen Desktop)

Best for: Mac users who want local control and verification.
Trade-off: requires sufficient local disk space for files.

On macOS, iCloud Drive appears directly in Finder. You can copy files to a local folder, then use Filen Desktop to sync them to your encrypted storage.

Ensure files are downloaded locally: If you use "Optimize Mac Storage," right-click folders in iCloud Drive and select "Download Now" to ensure files are actually on your Mac.
Create a staging folder: Make a new folder on your Mac (e.g., "iCloud-to-Filen") outside of iCloud Drive.
Copy files: Drag files from iCloud Drive in Finder to your staging folder. Wait for the copy to complete.
Install Filen Desktop: Download and install Filen Desktop for macOS.
Set up sync: Configure Filen Desktop to sync your staging folder to a destination in Filen.
Verify and clean up: Once sync completes, verify files in Filen, then delete the local staging folder to free space.

Benefits of this approach

Full visibility into what's being transferred.
Easy to reorganize files before they reach Filen.
Pause and resume capability through Filen Desktop.

Watch out for

Files showing cloud icons — these aren't downloaded yet.
Running out of disk space on smaller Mac drives.
Accidentally syncing the iCloud Drive folder itself.

Optimize Storage tip: Go to System Settings → Apple ID → iCloud → iCloud Drive and uncheck "Optimize Mac Storage" temporarily to ensure all files download locally.

Method 3: Cloud-to-Cloud Transfer with CloudsLinker

Best for: large libraries, Windows/Linux users, hands-off migration.
Trade-off: requires authorizing third-party access to iCloud.

CloudsLinker can connect to iCloud Drive and transfer files directly to Filen without downloading to your computer. This is the fastest option for large migrations or when local bandwidth is limited.

How it works

Connect your iCloud account as the source.
Connect your Filen account as the destination.
Select folders and start the transfer.

Why choose this method

No local storage needed.
Transfers continue when your device is off.
Works from any platform, not just macOS.

Step-by-step setup

Open CloudsLinker and create a new transfer task.
Add iCloud Drive as the source. You'll need to authenticate with your Apple ID.
Add Filen as the destination. Enter your Filen credentials (enable 2FA first for security).
Browse your iCloud Drive and select the folders to migrate.
Choose transfer options. "Skip existing files" is recommended for first-time migrations.
Start the transfer and monitor progress from the dashboard.

Recommended settings

Skip existing files to prevent duplicates.
Use file filters to exclude .DS_Store and system files.
Start with a test folder before full migration.

After the transfer

Verify folder structure and file counts in Filen.
Check error logs for any failed transfers.
Save the task for incremental syncs later.

Test with a small folder: Validate the process works before moving your entire library.
Consider app data: Some iCloud data is app-specific and may not transfer cleanly.

FAQ

Yes, if you've enabled "Desktop & Documents Folders" in iCloud, these appear in iCloud Drive and can be transferred like any other folder.

iCloud Photos is a separate service from iCloud Drive. For photos, see our Google Photos to Filen guide or export photos using the Photos app before uploading to Filen.

Yes. Install iCloud for Windows to access iCloud Drive in File Explorer, then copy files to a local folder and upload to Filen. Or use the cloud-to-cloud method which works from any platform.

App-specific data stored in iCloud (like app settings and databases) may not transfer cleanly. Regular documents, photos, and files in iCloud Drive will transfer without issues.

Conclusion

The best iCloud Drive to Filen method depends on your data size and how integrated you are with Apple's ecosystem. For a few folders, the browser route is simple. If you're on a Mac and want local verification, using Finder as a bridge works well. For large libraries or cross-platform users, CloudsLinker handles the transfer in the cloud without tying up your device. Start with a test folder, confirm everything looks right in Filen, then move the rest.
