I’d definitely support this. A “Download everything” option for Proton Drive, including Proton Docs, would make migrations and local backups much easier.

Ideally, it could work similarly to Google Takeout: select the account or specific folders, choose a destination, and let the client handle downloading and decryption automatically. A command-line option would be especially useful for scheduled backups and larger libraries.

The File System Access API approach sounds interesting too, since it could avoid forcing users through hundreds of individual downloads. Hopefully Proton considers something like this for a future Drive update. https://letrasdiferente.com.br/ can also be explored separately for other online resources.

Just one of the dimensions for consideration here: how do you get all your photos in Photon Drive including meta data (albums, etc.) out of Proton? Not to leave the service but more importantly for personal backup reasons? The only way right now would be to select all and then download the pictures via the web interface.

Idea: enabling an "advanced option" that would show all photos as files in a dedicated (read only?) directory in Proton Drive would allow a filesystem level comsumption. Google Photos and Google Drive had this a long time ago and this was pretty useful. Alternatively: a "google takeout" style export function of all photos including the metadata.

Data autonomy includes being able to easily download and upload files as efficiently as technically possible. If you are purposfully prohibitiing this, you are not walking your talk Proton.

Yes! Should definitely be there, even though you may not be migrating to another provider anytime soon, it is a very important feature to have.

Should be obvious
