I'd love this, specially if it is something decentralized like storj.io. It would be cheaper to mantain, equally as private and nice for everybody. Keep going team protonmail!!

+1 for file storage

Please add!

This would be great as I wouldn't have to rely on any other service anymore.

A complete Proton suite of E-mail, Contacts, Calendars and Cloud (with the secure environment we came here for) would be absolutely fantastic.

That would be great to be able to edit collaboratively some document and to share them with security. Content management and project management would be great too.

I completely agree. This is what I truly need in addition to secure email. While I would love for this to be included in the basic package, I would happily pay for a service like this. Maybe inclusion in the Plus package to cover initial costs of development and support? I'd support a Kickstarter/Indie Gogo campaign as well.

Spideroak. It was even recommended by snowden (2013 or so?)

i use spideroak. it was recommended by snowden years ago and works fine for sync. it´s also zero-knowledge.

honestly i would it more to see the protonmailteam collaborate with spideroak than creating their own thing... you can´t build the best of every solution, just get someone who is already doing it fine and work with them. :P

Great to see this move into 'planned' status! Thanks!

Hello, any update on this feature?

Thanks!

This a thousand times over! Email is a tremendous step forward for security. But it only facilitates the secure flow of information. Which for a vast majority involves documents (Pdfs, Word, Spreadsheets, etc). Being able to interact with this and send them securely would help the minimalist transition from Google. Obviously, having a mobile app as well. This function needs the love and would really help protonmail grow from individual users and business.

Would move all my files to protondrive if this feature existed.

Cloud storage in Switzerland of course not elsewhere would be great !

I use Pcloud drive (encrypted ,made in swiss... )

There should be a way to drop large files into someone's account. I suggest that there would be a "Google Drive" like service with collaboration; each file would count towards the user's storage limit, but each file would be encrypted with a random key (probably AES - 256) which would be shared to other users accounts when the owner wants to collaborate through a specially marked PGP message, keeping everything end-to-end encrypted. I don't know how to secure unlisted files (most likely used for secure images); maybe a hash table, that gets accessed and decrypted client-side.
Generally, a file storage system will make Proton Mail much more enjoyable.

I would love a open-source cloud storage with end to end encryption, just like ProtonMail is. So far, I have been putting files into a 7z file and then emailing them to myself, but 500mb (free) is too small for large files, like video files.

Also, in case you didn't know by now, Mozilla now owns Pocket and it is open-source now.

I use sync online storage, excellent privacy

Mega.nz do it and 50 GB free

Yes, there's Dropbox, Google Drive, Microsoft Cloud, Mega.NZ, Tresorit, Box.com, and others. Every ProtonMail Premium account would benefit by having its own encrypted file storage with one special nuance: Make sure it is lightning fast and capable of loading extremely content rich files (graphics, photos, alternative text) along with encryption.
