Filen review

Filen is cloud storage for people who want files encrypted on their devices before they reach the cloud. The product description says it uses client-side, zero-knowledge encryption with AES-256-bit encryption. Its apps cover web, desktop, mobile and CLI, with file syncing, sharing, encrypted notes and chats, plus a network drive that presents cloud files like a local disk.

Syncing supports five modes, and the network drive includes Smart Sync. Notes support rich text, code, Markdown and checklists. Files can be organized in list or grid views. That makes Filen more than a place to park encrypted files, though the published materials don’t detail how its notes, chats or sharing compare with dedicated tools.

There is a free plan, but the published pricing information does not state its storage allowance. A Reddit thread describes it as 10 GB; treat that as a user report, not a confirmed current plan limit.

The main draw is the combination of client-side encryption and low listed monthly prices. According to the pricing page, Pro I costs €1.99 per month for 200 GiB, while Pro II is €3.99 for 500 GiB. Both include unlimited bandwidth, unlimited uploads, client-side encryption, and unlimited notes and chats. That is a straightforward price ladder for personal storage, rather than a bundle that requires buying unrelated services.

For more capacity, the page lists Pro III at €8.99 per month for 2 TiB and Pro X at €39.99 for 10 TiB. Plans can be stacked; the pricing information says two Pro X plans provide 20 TiB. Annual billing is offered, but the annual prices are not published, so we can’t compare the yearly discount.

The product also covers practical extras: five sync modes, a network drive with Smart Sync, and encrypted notes and chats. Reddit users praise the value and report using Filen alongside other storage services. One thread describes the free plan as 10 GB, though the current free-plan allowance is not specified in the published pricing details.

The biggest concern in the published user reports is what can happen when storage goes over its limit. In one Reddit thread, a subscriber said usage reached 2.01 TB on a 2 TB plan and that Filen deleted all server-side data after sending an email warning. The user said they had local backups and could not recover the cloud files. This is one account, not a published policy, but it is serious enough that we would not treat Filen as the only copy of important data.

Other Reddit commenters report upload problems, crashes, and a desktop browser upload failure. Those are anecdotes, not established service-wide limits, but they complicate the pitch for a sync product. The published sources don’t specify a grace period, recovery window, or exact behavior after an overage, so check current terms and keep an independent backup.

Price transparency is also incomplete: annual billing is available, but annual prices are not published. The free plan’s storage cap is likewise not stated on the vendor's site.

Filen lists a free plan, but the published pricing details don’t state its storage allowance or limits. Paid monthly prices start at €1.99 for Pro I, which includes 200 GiB. Pro II is €3.99 for 500 GiB; Pro III is €8.99 for 2 TiB; and Pro X is €39.99 for 10 TiB. Every listed paid plan includes unlimited bandwidth, unlimited uploads, client-side encryption, and unlimited notes and chats.

The biggest jump is from Pro III to Pro X: €31 more per month for an additional 8 TiB. Filen says plans can be stacked; two Pro X plans provide 20 TiB, though the pricing details don’t say whether stacking changes the per-plan price. The page shows an annual billing option but doesn’t publish annual prices, so we can’t calculate the yearly discount or total. Check the current checkout price before committing, and don’t assume the free plan has enough room for a full migration.

Moving to Filen means transferring files into a service that encrypts them client-side. The published details list web, desktop, mobile, and CLI apps, plus sync modes and a network drive, but don’t document a bulk migration tool or the time a transfer may take. For a large library, plan for a staged upload and keep the original files until you’ve checked the transferred copies.

Leaving requires the same caution in reverse: confirm you can retrieve files in a usable form before ending a subscription. The published materials don’t specify export formats, bulk-download limits, or an account-exit process, so check those points with Filen before moving a large archive. That’s a practical lock-in concern, not evidence that files can’t be exported. The review material flags user-reported risk, but includes no Reddit posts or specific reasons people leave; we can’t responsibly attribute a particular complaint to Reddit. Keep a separate backup either way.
