What is Filen?
Everybody can claim to be the most secure cloud storage service. We at Filen like to be transparent. So how does everything really work under the hood? Well, it's quite simple. When you upload a file to Filen's cloud storage, you actually don't upload a file, you upload chunks of encrypted text. Before you initiate an upload, your browser chunks your file into 1 MB pieces, encrypts them using AES encryption and then sends the encrypted string to our servers. That way the actual file never leaves your computer. Even file names and metadata are encrypted.
When downloading a file your browser requests all chunks of the file from Filen's servers, decrypts them using the decryption key and then rebuilds the whole file again.
This way you can be sure that your file is always secure and not readable by anyone unless they have the decryption key. Not even we know what you have uploaded.

raw. Just growing. Concept is good, realization is not. Require more time & efforts to make it ideal. Strange business model. Probably funded by some tech company. Cheap price affect quality.
In 2021 - xss on website, and complete critic about their product JS code quality on front end.
In 2022 - i personally faced big issues with download speed from their servers in Germany to Europe. After 2GB or 3GB file size the speed drop from 100mbit/s to around 1Mbit/s which is NOT okay.
These guys need to do a lot of work to make their service great. It has whole power for that. They just need more time, more clients.
One of the best E2EE Cloud Storage Service with open-sourced clients.
Last update was in August 2021...
You can go their GitHub page since they are open source and that is there repository. They are a veriified company and they show code being actively worked on by about 5 people.

Iam all about privacy and so far they have proven that they care about it, they also listen to the community. Good prices, looking forward to see them grow
Going up on score for Filen. Not necessarily because they have become better, just how many issued others have had implementing system like they have. Other services are easier but have some catch to their zero trust and E2EE . Filen may not be the most elegant solution but it does actually get the job done.
I like Filen because of its end-to-end encryption, privacy and open source apps. Also, you get 10 Gb free
Open source, hosted in Germany, steady improvements. Looking forward to seeing them get better and better!
