Proton Drive: plan how to share a manuscript before uploading it

Proton Drive is a cloud storage service that describes its file protection as end-to-end encryption. It also provides file-sharing features. For a writer exchanging a manuscript, this makes it relevant to the question of how a draft reaches the right collaborator without becoming an uncontrolled public link.

Test how a shared manuscript reaches its reader

For feedback on a draft, create a clearly named review copy and decide who should receive it. Check the sharing options currently available in your plan, then test access from a separate browser session before sending the real link. After feedback, review who still needs access. Keep an independent backup of your own working file. Treat the recipient as someone who may retain a copy; account security and careful sharing remain necessary even when storage uses encryption.

Encryption does not undo a recipient’s download

Read the current plan details, recovery guidance and sharing documentation before relying on a workflow. Encryption does not prevent an authorised recipient from copying or forwarding what they can read. Keep an independent backup and protect your account. For confidential work, agree on handling expectations with your collaborator rather than assuming the storage tool alone establishes them.
