Filen Review

Our initial Filen review found the service to be an exceptionally secure and private encrypted cloud storage. The biggest issue was a lack of cloud features, making Filen a bare-bones service. We are revisiting Filen to see what is new, updated or changed.

The last time we did our Filen review, it was a new cloud storage provider trying to break into a crowded and competitive market. We found Filen to be exceptionally secure and private. However, what Filen offered in data protection, it lacked in cloud features, especially compared to the best cloud storage services.

Key Takeaways: Filen

  • Filen puts the security and privacy of its users first with end-to-end private encryption on all accounts.
  • If you’re looking for a feature-rich cloud storage provider, Filen comes up a bit short.
  • Filen offers very affordable paid plans, including lifetime options, with a variety of storage amounts.
  • File versioning, file size and bandwidth isn’t limited with Filen.

Filen has had some time to mature as a cloud storage service, and upon initial examination, it has updated the overall experience. We noticed a sleeker user interface and some added features that provide its users with plenty of customization and flexibility, as we will cover below. It’s time to revisit Filen and see what’s new and what’s changed.

If you’re looking for a short answer from our hands-on testing, here it is. From a security and privacy perspective, Filen still delivers. When it comes to productivity, though, Filen still feels like it’s lacking. Keep reading for more details.

55 % – Fair

Filen provides what one would expect from a cloud storage service: the ability to upload, store and share files. That was the basis of what Filen offered when we first reviewed the service, and overall, there hasn’t been much of an update to the features since. 

Filen was created on the pillars of security and privacy. We will go into more detail in those respective sections below. However, it’s nice to know that the encryption chain remains intact when sharing files with other Filen members. Even when sharing files with others outside of Filen, you can add additional layers of protection.

What you won’t find with Filen are any third-party integrations of any kind. This is often the case or trade-off with a highly secure and private cloud storage service. However, even competitors like have some inter-functionality with a few external app connections. Native Filen apps aren’t a thing either (such as Dropbox Paper).

File Previews

Previously, Filen didn’t offer many file types for preview. However, that’s changed now, as you can preview multiple file types. For example, videos play back directly in the web browser. The same is true with pictures, as you can preview them, although there are no image editing tools.

Other file preview types include PDFs as well as Excel and Word docs, making it easy to look at a file, especially if you have many documents. However, slideshow presentations (such as Office PowerPoint or Google Slides) are not supported with file previews.

filen file preview
File previews include photos and videos (with web browser playback). However, slideshow previews are not supported.

From our testing, editing documents or other file types is nonexistent in Filen with the exception of text files. This is especially convenient for those who program or work with code, as HTML can be edited within the web browser. If you are familiar with code editor programs like Visual Studio Code or Brackets, text editing within Filen will look and feel familiar.

Still, using the text editor is best for only minor changes, as it is an extremely simplified coding experience. It comes with a basic auto-complete feature for many common programming languages including HTML, CSS and JavaScript.

filen text editor
Coders and programmers will feel at home with Filen’s built-in text editor.

The text editor is smart enough to nest commands within commands in a visually familiar way. However, there aren’t any advanced coding features, and this functionality won’t replace a dedicated coding editor.


The “favorites” tab is a small but nice feature that allows the user to identify different files and access them quickly. It works by selecting the “favorite” option from the dropdown menu on a file (right-click). Favoriting a file places a little heart next to it. 

filen favorites
Any files you designate as favorites show up in the “favorites” tab for easy access.

Any file you designate as a favorite shows up in the left sidebar under the “favorites” tab. Since you can customize the structure and organization of your folders and files — more on that in the ease of use section — designating files as favorites, especially if you have a lot of files, is certainly a time-saver.

File Versioning

Filen doesn’t limit file versioning on an account, which provides some flexibility to the end user. However, although you can keep as many versions of a file as you’d like, and for an infinite amount of time, all file versions count against your overall storage (this includes deleted files as well). 

Additionally, you can’t set or customize file versioning, meaning you have to manage them manually. This could become cumbersome with a large repository as you’ll need to delete individual file versions to free up space. The other option is to delete all file versioning data in the account settings. There’s no option to pick and choose; if you delete something by mistake, this action is permanent.

Free Plan


90 % – Excellent

It’s easy to try Filen out, as a free account has 10GB of storage. Perhaps even better is the fact that the free plan isn’t a stripped-down version of a paid plan. The free plan includes all the features of a paid plan with less storage space.

Filen’s pricing plans are exceptionally affordable and come with various storage sizes. The Starter plan offers annual or lifetime payment options. Both have 100GB of storage for $11.99 per year or a one-time payment of $29.99. For comparison, Icedrive offers a 100GB plan for $3.99 per month (one-year plan) or a storage of 512GB for a one-time payment of $179 under its lifetime plan.

If monthly paid options are more your speed, the Pro I plan comes with 200GB for $1.99 per month. The Pro II plan increases storage to 500GB at $3.99 per month while the Pro III is 2TB for $8.99. Annual options for the same three plans are $19.99, $39.99 and $89.99, respectively. 

filen pricing
If the 10GB free service isn’t enough, Filen offers affordable paid plans.

Filen’s three Pro plans are available as lifetime offers (check out our best lifetime storage article), with the same amount of storage as the recurring payment plans. The Pro I plan has a one-time cost of , while the Pro II plan is and the Pro III costs . 

Filen’s lifetime plans compare well against its competitors, such as pCloud. pCloud’s comparable lifetime plans include its 500GB Premium plan at a one-time fee of $199 and the Premium Plus 2TB plan costing $399.

If you are undecided whether to purchase a plan with Filen, it offers a 14-day money-back guarantee.

Ease of Use

80 % – Good

Immediately upon creating a Filen account or logging in, the look and feel of the web interface emulates the finder on Mac or file explorer on Windows. It’s a familiar look and feel, which makes navigating around a Filen account easy, especially for beginners. The UI has a simplistic quality, which isn’t necessarily a negative, in our expert opinion. 

Sticking with the desktop folder structure, you can drag and drop files for upload or into folders within your account. This makes it easy to organize and structure your folders and files as you like. Another nice feature within the settings is the option to enable dark mode.

filen account
The Filen UI looks like a finder or file explorer, complete with a trash can for all your deleted files.

Filen maintains its aesthetics across its mobile and desktop apps. The most notable aspect of the desktop app is that it functions more like an extension of the web browser. It runs almost in the background, and unlike competitors like or Dropbox, Filen doesn’t create a dedicated folder on your device. 

This means that you can’t interact with the files you sync with your account in a specified place, so you’ll have to remember which folders and paths you create.

filen desktop app
The desktop application functions like an advanced settings interface, including customizable file sync.

The desktop application expands your settings and options on the web interface, the most notable being the sync options and configurations (more on file sync below). You’ll see that Filen doesn’t throttle your account within the network settings. You can, however, configure how much bandwidth your account uses to upload and download data.

It’s worth noting that the desktop app (and the mobile app) are not exact copies of your account on a web browser, specifically with regard to settings. For example, you can access the “security” and “invite” tabs on the web, which are not options on either of the apps.

filen mobile app
Filen improved the mobile app experience, which includes automatic camera uploads.

Filen Mobile App

The mobile app’s homepage feels cluttered, especially with the selectable links along the top row. However, it’s organized the same way you set it up on the web interface, making finding documents easy. Most notable with the mobile app is the dedicated photos section.

Our previous review of Filen noted that the mobile app didn’t have automatic photo uploads from a mobile camera. That isn’t the case this go around, as you can enable camera uploads either through the “photo” tab or within the app settings.

Much like the desktop app, the mobile app provides plenty of setting options that let you configure your account. Some examples include the ability to hide thumbnails or file names, to use WiFi for uploads/downloads or set up biometric or PIN code login processes. Specific to the camera upload, options include enabling live photos and videos or creating albums.

File Sharing & Syncing

85 % – Very Good

File sharing and file sync are two areas where Filen separates itself from its competitors. On the surface, file sharing works the same as with other providers, while Filen has more file sync customizations than many comparable products on the market.

File Sharing

From our experience, file sharing with Filen looks and feels similar to other cloud storage providers, especially at first glance within an account (we list the best cloud storage for sharing). You can share any file you want or even entire folders. Right-clicking on either type allows you to choose “share” or “link” from the dropdown menu. Here’s where things differ with Filen compared to most of its competitors.

Filen lets you share files using a single email address or by creating a public link. To share a file using an email address, the recipient must be another Filen user.

When you choose the “share” option, you will get an error message if you enter the email address of someone without a Filen account. Filen does this to ensure that the highest level of encryption protects your shared file. 

Any files you do share with other Filen users won’t require any additional layers of protection; you only need to enter an email address.

filen file share
Link sharing within Filen is the only way to share files with non-Filen contacts.

If you want to share a file (or folder) with someone not associated with a Filen account, you will have to use the “public link” option from the dropdown. This will create a shareable link that you can customize with an added password and expiry options of up to 30 days. You can also enable the link and enable or disable the download option.

File Sync

Filen lets its users decide how file sync works within an account. It’s not the first cloud storage provider to allow customized file sync options. However, having tested many cloud storage services, Filen takes a unique approach by providing several choices with its “sync mode.” Check out our article on the best cloud storage with file sync to learn more.

The first step to customizing your sync experience happens by creating a folder to sync with on your computer. It’s important to note that the only way to set up sync options is through the desktop application. Once you create a sync path (for example, connecting your documents folder to your Filen account), clicking the gear icon on the path opens up a host of choices.

Filen supports selective sync for each path you create. If you have multiple folders in the sync path, you can select and deselect them as needed. You also have a pause option to temporarily halt syncing with your Filen account. 

Another option in the settings is “.fileignore.” You can edit this to determine which types of files you don’t want to be synced. If you are familiar with .gitignore, this function works the same way.

From our testing, the real highlight of Filen’s file sync is the sync mode option. Sync mode lets you choose between five possibilities:

  • Two Way — Mirrors any action taken on a device or within an account
  • Local to Cloud — Uploads changes made on a device, but not in the cloud
  • Cloud to Local — Updates changes made in the cloud, but not on a device 
  • Local Backup — Uploads data to the cloud; does not delete anything
  • Cloud Backup — Downloads data from the cloud; does not delete anything

 Filen lets you choose the sync mode from five options and supports selective sync.


60 % – Fair

When we tested the service, we found that Filen slightly improved its overall speeds from the last time we tested it, but only marginally. While uploads were a strain on CPU resources in the past, that was not the case this time around, as Filen stayed below 50% usage.

We conduct all speed tests from our servers in Dublin with a max speed of 1 Gbps. We cap speeds at 100 Mbps to ensure a standard control baseline. Uploads and downloads happen twice using different file types that combine to 5GB of data. 

1st test2nd testAverage:
Upload speed0:19:300:22:200:20:55
Download speed0:10:050:09:300:09:47

Typically, a trade-off with a highly secure cloud storage provider is slower than average speeds. That is still the case with Filen. Filen won’t be accused of being the fastest cloud storage available and you could run into delays transferring large files. 


100 % – Excellent

It is apparent immediately after navigating to Filen’s homepage that it takes its account holders’ security (and privacy) very seriously. Security is the pillar Filen was built on, and it’s the primary appeal of the cloud storage provider. 

Before getting into the specifics of how Filen protects your data, it’s important to point out that this is an open-source program. Being open source means that Filen can’t hide malicious or nefarious code, since anyone who cares can take a look. Additionally, open source builds trust between the service and the customer.

filen security
Filen makes it clear that all its accounts are zero-knowledge and client-side encrypted.

All accounts with Filen have client-side end-to-end encryption (as opposed to encryption happening on the server side). Client-side encryption means that your files are encrypted before transfers from your device, which protects them during uploads. Filen uses AES 256-bit encryption for every individual file.

Filen separates and encrypts your data while stored on its servers and reassembles your files only when you authorize a download. This process happens using an encryption key derived from your password. Additionally, according to Filen’s publicly available security documentation, it encrypts your account metadata and file names.

Account Security Tools

Additional security steps on an account include enabling two-factor authentication, exporting master keys and requesting your account data. Enabling two-factor authentication is as simple as scanning a QR code and increases your account protection while logging in.

Exporting your master keys lets you recover your account in the event you lose your password or for any other reason. Without the master keys, you won’t be able to access your account, since Filen doesn’t store this data. If you change your password, be sure to export a new set of master keys.

Overall, Filen’s security is as good as it gets. We gave it a perfect score in our last review and see nothing lowering the bar.


100 % – Excellent

Filen doesn’t let itself down with its privacy policy or practice. Unlike a few cloud storage providers with excellent security but questionable privacy (like Google Drive), Filen offers excellent privacy. All accounts have zero-knowledge encryption, even the free 10GB option. Zero-knowledge means only you can access your account, as Filen couldn’t access it even if it wanted to.

Fortunately, Filen doesn’t want access to your account, as its easy-to-read, comprehensive privacy policy indicates. Filen’s privacy policy has grown since our last review, but thankfully it’s not full of legal jargon. It describes what data it collects on you (basic and necessary information such as your email or IP address) and how Filen uses it. Other sections include your rights, cookies, payments and analytics.

filen privacy
Filen’s privacy policy is one of the easiest to read and comprehend, as it is clear about your rights and how it uses your data.

As a Germany-based company, Filen fully complies with the General Data Protection Regulation (as evidenced by the ability to download your data at any time). For example, clicking “request account data” creates a downloaded file of the information Filen has connected to your account. Additionally, If you decide your time with Filen is over, you can have it delete any data on you. 

Customer Support

50 % – Poor

Getting help with Filen starts (and mostly stops) on its dedicated support page. It provides a list of FAQs that are searchable, which is about the extent of its support options. If you don’t get the keyword correct, you won’t find the answer you’re looking for. The FAQ list is not extensive or exhaustive, although there are quite a few. 

Further down the page, a couple of boxes contain links to additional FAQs centered around pricing or app help. These questions and answers seem to be separate from the list of FAQs found on the support page.

filen support
Filen’s dedicated customer support page is a list of FAQs and a link to submit a help ticket.

A third box touts the availability of 24/7 customer support. However, Filen really wants you to help yourself, as the link in the “contact us” box tells you to “please look up your issue first.” If you click on that text, it will take you to the top of the page and back to the search bar. Scrolling down will reveal the same text. Only after you attempt to search for an answer will the text change to “submit a ticket.”

Submitting a ticket for help opens what looks like a live chat feature, but it isn’t. You’ll need to wait until a customer service rep replies and then again if you have any further follow-up questions. It takes about a day to get a response with the ticketing system, which is in line with the automated email indicating 24 to 48 hours.

The lack of a live chat or even a community-supported forum limits how much help you can get on your own. 

The Verdict: Is Filen Worth It?

The decision to use Filen or not comes down to what you need from a cloud service. If you’re looking for collaborative tools for productivity and team-based projects, Filen won’t check many of those boxes. However, if stringent security and privacy are your most important factors, Filen is a top option and well worth using.
