Ich würde auch gerne meine Datenbanken von Devonthink auf dem Protondrive synchronisieren. Wäre sehr hilfreich, wenn das in absehbarer Zeit möglich wäre.

This would make it possible to sync my data across devices with other tools such as Zotero, Obsidian.

WebDAV to sync DEVONthink with Proton Drive please! Here is why:

1. Enhancing the usability of Proton Drive: Introducing WebDAV support would enable synchronisation with popular document management applications like DEVONthink. This would make Proton Drive a more versatile tool, attracting a larger number of users.

2. Expanding the user base: Many users rely on DEVONthink and other WebDAV-supported applications to organise their data. Supporting WebDAV would make Proton Drive more appealing to these users, potentially increasing subscription numbers.

3. Improving data security: Proton Mail is highly regarded for its advanced security features. Adding WebDAV to Proton Drive would allow users to securely sync data from applications like DEVONthink, further strengthening Proton Mail’s position as a leader in privacy and data security.

4. Integration with external applications: WebDAV is a widely used protocol that allows integration with various applications. Adding WebDAV support to Proton Drive would make it easier for users to collaborate with multiple document and data management tools, thereby increasing the value of Proton Drive within the software ecosystem.

5. Increasing user loyalty: Providing support for WebDAV could increase satisfaction among existing users who utilise DEVONthink and similar applications. This, in turn, could enhance user loyalty, making them more likely to continue their subscriptions to Proton Mail and Proton Drive.

Agree with comments below. Can a tech lead explain why this is not technically doable, or (hoping) perhaps it's on a roadmap and soon to be implemented?

I have a boox tablet, for reading and note-taking, and it would be nice to connect the two in a way to back-up/share my notes and books.

Wow 2 years of a company not adding a basic-*** feature that everyone needs. Might as well just delete Proton Drive.

Webdav would be very handy for syncing my Zotero library. Currently, I depend on other cloud services for this. If Proton implements Webdav in Proton Drive, I could switch completely to it, and ditch other services once and for all.

Seriously, this is the only thing stopping me from starting to pay for a plan by literally going all out on Proton Unlimited. Once they start implementing WebDAV (which is probably quite tricky due to the E2EE) I can finally have it sync with my Seedvault backups and function as a feasible personal private secure "off-site" storage solution.

I need WebDav support in order to move my KeePass database to the Proton cloud. I know, there is a KeePass plugin, which does this, but for me this is an insecure link in the chain.

Facilitates automatic backup from NAS (Synology, Qnap, etc.)

Like many others I guess, I would definitely subscribe to Proton-unlimited, when Proton drive would support web-dav. Now I have to stick to strato-hidrive. So please follow up on this request.

WebDAV for Joplin and more

Would make it a real competitor to google and other cal/contact/file solutions. It's one of the things that has me on the fence about buying premium proton for personal use.

without webdav, no use for me. The goal is to replace googledrive for my syncro with a NAS.
Without that, I'll have to stay with google 😭

PLEASE add this

Awaiting this feature as well

Like other commentors, my immediate use case would be to sync Joplin note databases, but there are half a dozen other applications that could allow me to do away with Apple, Google, and Microsoft cloud services. Can't wait for the day.

This would allow me to use the terrabytes I have on here for a lot of purposes, freely : Proton would become the center of everything I do that need storage;

Webdav would facilitate connecting ProtonDrive to OnlyOffice. This would be a big step towards replacing the entire Google Docs suite. I vote this as a priority feature.

As others below, I arrived here after searching for webdav support for Proton Drive so I can sync Joplin. Currently using OneDrive, which I'd love to ditch.
