Post-Quantum Privacy for Your iCloud Files: Moving iCloud Drive to Internxt

Q: "Why does the Internxt connection require an Ultimate plan?"

"Internxt exposes third-party access through its rclone integration, and Internxt enables that integration on the Ultimate tier (5 TB). Free, Essential and Premium accounts are rejected at connection time — this is Internxt's gating, not CloudsLinker's."

Q: "What is the largest single file that can make this move?"

"iCloud Drive itself accepts files up to 50 GB, but Internxt's rclone-based access caps individual files at 40 GB. Anything between 40 and 50 GB — typically video exports or disk images — needs splitting before the transfer or a different destination."

Q: "I have Advanced Data Protection enabled. Does that change the transfer?"

"No. ADP encrypts iCloud data end-to-end for Apple's servers, but a session you authorize with your Apple ID and a trusted-device code still reads files normally — that is how iCloud.com works under ADP with web access turned on. Make sure 'Access iCloud Data on the Web' is enabled in your iCloud settings first."

Q: "How does CloudsLinker sign in to iCloud Drive?"

"With your Apple ID and password, followed by the standard 6-digit verification code Apple pushes to your trusted devices. The session behaves like an iCloud.com login; revoke it anytime from your Apple Account's device and session settings."

Q: "Is my folder structure preserved in Internxt?"

"Yes. Internxt Drive is a normal hierarchical file system, and the transfer recreates your iCloud folder tree inside the destination folder you pick. Encryption happens per file on Internxt's side without flattening anything."

Q: "What happens if my Internxt plan runs out of space?"

"The transfer stops writing when the destination quota is exhausted and the Task List shows which files did not copy. Ultimate includes 5 TB, which covers most iCloud libraries — the 2 TB iCloud+ tier maxes out well below that."

Q: "Can I move only some folders and keep the rest in iCloud?"

"Yes. You tick individual folders on the source side, and filters narrow the selection further by file type, size or modification date — sensitive documents only, for example, leaving photos and app data where they are."

Q: "How is each connection secured?"

"The iCloud session uses Apple's own login plus two-factor verification; the Internxt connection uses your account credentials and optional 2FA, and files are encrypted client-side by Internxt's protocol before storage. CloudsLinker transfers over TLS and stores access tokens encrypted."

Move iCloud Drive files to Internxt's zero-knowledge, post-quantum encrypted storage. Manual export and a server-side cloud transfer compared.

Introduction

Internxt encrypts every file with AES-256 before it leaves your device, holds no readable copy of your data, and has already deployed post-quantum cryptography — the Spanish company cannot decrypt what you store even under legal compulsion. That design attracts one specific user: someone whose iCloud Drive holds tax records, medical scans or legal documents, and who wants encryption that does not depend on trusting the provider. Apple's standard iCloud protection keeps decryption keys on its own servers unless you enable Advanced Data Protection, and even then the ecosystem assumes you stay inside Apple hardware. This guide covers two ways to make the move: a manual export through iCloud.com, and a server-side transfer with CloudsLinker that handles large libraries without touching your local bandwidth.

Frequently Asked Questions

What is iCloud Drive?

iCloud Drive is Apple's file storage layer, woven into macOS Finder and the iOS Files app. Every Apple ID gets 5 GB free — shared with device backups and Photos — with iCloud+ tiers from 50 GB ($0.99/mo) to 12 TB ($59.99/mo).

5 GB free, shared with backups and Photos
iCloud+ tiers: 50 GB to 12 TB, monthly billing only
50 GB maximum single file size
Keys held by Apple unless ADP is enabled

What is Internxt?

Internxt is a Spanish zero-knowledge cloud: files are encrypted with AES-256 on your device before upload, the company holds no decryption keys, and its stack already uses post-quantum cryptography. Plans run 1 TB / 3 TB / 5 TB, with one-time lifetime purchases as an alternative to subscriptions.

Zero-knowledge AES-256 + post-quantum encryption
Essential 1 TB, Premium 3 TB, Ultimate 5 TB
Lifetime plans available (one-time payment)
Third-party access on Ultimate only; 40 GB per-file cap

Preparing to Transfer from iCloud Drive to Internxt

Turn on Access iCloud Data on the Web in your iPhone or Mac's iCloud settings — without it, neither iCloud.com nor any transfer tool can read your Drive. Decide what actually needs zero-knowledge storage: documents, archives and finished projects benefit; files that Apple apps open daily (Pages documents in active edit, app-synced data) should stay. Check for any single file between 40 and 50 GB — iCloud allows them, Internxt's third-party access does not — and split or exclude those. Finally, confirm your Internxt account is on the Ultimate tier, since that is the only plan Internxt's integration accepts for external connections.

Method 1: Export via iCloud.com and Re-upload

Step 1: Download from iCloud.com

Sign in at iCloud.com, open Drive, select folders and click the download icon. Folder selections arrive as ZIP archives; large libraries split into several.

Step 2: Upload into Internxt Drive

Extract the archives, sign in at drive.internxt.com, create a destination folder and drag the extracted content in. Encryption happens in the browser during upload, which makes this slower than a plain cloud upload of the same size.

Every byte crosses your connection twice, plus browser-side encryption overhead. Fine for a documents folder; painful for a couple hundred gigabytes.

Method 2: Transfer iCloud Drive to Internxt in the Cloud

An authorized iCloud session, written straight into the vault

CloudsLinker signs in to iCloud the same way iCloud.com does — Apple ID plus a trusted-device code — and writes each file into Internxt through its encrypted protocol, all server-side. No ZIP archives to re-assemble, no double pass over your home connection, and the folder tree arrives intact.

Step 1: Connect iCloud Drive

Click Add Cloud → iCloud Drive. Enter your Apple ID and password, then the 6-digit verification code that appears on your iPhone, iPad or Mac. If no code arrives, generate one manually from your device's Apple Account security settings.

Step 2: Connect Internxt

Click Add Cloud → Internxt. Enter your Internxt email and password, plus your 2FA code if enabled. The dialog rejects Free, Essential and Premium accounts — Internxt opens third-party access only on Ultimate.

Step 3: Configure the Transfer

In the Transfer section, set iCloud Drive as the source and tick the folders holding your sensitive documents. Set Internxt as the destination and choose a target folder. Filters restrict the job by type, size or date — for instance, PDFs and images only. Copy mode leaves iCloud untouched for verification before any cleanup.

Step 4: Start and Monitor the Transfer

Start the job and watch the Task List — files done, current speed, and anything skipped. The copy runs entirely on CloudsLinker's servers; closing the browser or sleeping your Mac changes nothing.

Comparing the Ways to Transfer From iCloud Drive to Internxt

Method	Ease of Use	Speed	Best For	Uses Local Bandwidth	Skill Level
iCloud.com export + web upload	Medium	Slow (double pass + browser encryption)	A few GB of documents	Yes — twice	Basic
CloudsLinker	Easy	Fast (server-side)	Full libraries, preserved folder trees	No	Basic

Practical Tips for Moving iCloud Drive to Internxt

Enable web access first: the 'Access iCloud Data on the Web' toggle in iCloud settings gates everything — iCloud.com and transfer tools alike read nothing while it's off.
Mind the 40 GB ceiling: iCloud accepts single files up to 50 GB but Internxt's third-party access stops at 40 GB. Hunt down oversized video exports and disk images before starting, not after.
Convert iWork documents: .pages, .numbers and .keynote files transfer as-is but open nowhere outside Apple's ecosystem. Export active ones to Office or PDF formats if you plan to leave Apple entirely.
Ultimate is non-negotiable: Internxt's integration rejects lower tiers at connection time. Upgrade (or use a lifetime Ultimate deal) before scheduling the migration, not during.
Expect encryption overhead on writes: Internxt encrypts per-file as data lands, so a 500 GB job runs somewhat slower than the same bytes into an unencrypted cloud. The Task List's speed figure reflects this.
Keep Apple-app working files in iCloud: anything an iPhone app syncs continuously (scanner apps, note attachments) re-appears in iCloud after you move it. Migrate finished archives, not live app folders.
Verify before downgrading iCloud+: spot-check files in Internxt Drive, then drop the iCloud tier — deleted iCloud files linger 30 days in Recently Deleted, giving you a safety window.

Conclusion

A few gigabytes of documents move fine through iCloud.com's download button and Internxt's web uploader — just plan around ZIP re-assembly. For a full Drive library, CloudsLinker connects to iCloud with your Apple ID plus a 2FA code and writes into Internxt's encrypted storage server-side, keeping folder structure intact. Two constraints to respect before starting: the Internxt connection requires an Ultimate plan, and no single file over 40 GB can cross in one pass. Files you actively edit on Apple devices should stay in iCloud; the archive belongs in the vault.
