Proton Drive

Proton Drive is Proton’s end-to-end encrypted cloud storage service. Blober connects to your Proton Drive through a browser-based login. No API keys or developer setup required.

Caution

Proton Drive support is currently in early access. All files are encrypted with PGP, so operations may be slower than other providers.

Capabilities

• ✅ Browse files and folders
• ✅ Download files (decrypted automatically)
• ✅ Upload files (encrypted automatically)
• ✅ Delete files (moves to Proton trash)
• ✅ View file metadata (filename, dates, size)
• ❌ Create folders
• ❌ Move/rename files

Prerequisites

A Proton account with Drive enabled (free or paid)

Setup

1. Go to Workflows → New Workflow
2. Select Proton Drive as source or destination
3. Click Open Proton Drive Login
4. A browser window opens. Sign in with your Proton account (email, password, and 2FA if enabled)
5. Wait for Proton Drive to fully load in the window
6. Blober captures your session automatically and the window closes
7. Start browsing or transferring files

Tip

Your session lasts approximately 12 hours. When it expires, Blober will open a login window so you can sign in again. No data is lost.

Multiple Accounts

Blober supports connecting multiple Proton accounts at the same time.

1. In a workflow, open the Proton Account dropdown
2. Click + New Account to connect another Proton account
3. A new login window opens. Sign in with a different account
4. Switch between accounts using the dropdown

Each account maintains its own isolated session. You can run workflows against different accounts in parallel.

File Organization

Proton Drive preserves your folder structure as-is:

/Documents/report.pdf
/Photos/vacation/IMG_001.jpg
/Videos/project-demo.mp4

File Selection

When browsing your Proton Drive, you can select:

• Individual files by clicking a single file
• Multiple files by checking several files across folders
• Entire drive by ticking the / (Entire Storage) checkbox

After making your selection, click Submit Selection to add the files to your workflow.

Performance

Proton Drive operations are slower than other providers because all data is end-to-end encrypted. Blober handles encryption and decryption automatically.

• Browsing is slower because each filename is individually encrypted
• Downloads are streamed and decrypted block by block
• Uploads are currently buffered in memory (streaming uploads coming soon)

Metadata

Each file includes the following metadata, available for use in Blober’s naming templates:

Field	Example
Filename	report.pdf
Created date	2026-01-23
Modified date	2026-05-10
File size	14.2 MB
File extension	.pdf

Troubleshooting

Login window stays open

Proton’s app takes a few seconds to fully load after login. Wait for the Drive interface to appear. Blober will detect it and close the window automatically.

”App did not become ready” error

This means Proton Drive’s web app didn’t finish loading within 30 seconds. Try again. The Proton servers may be slow, or your connection may have timed out.

Session expired during transfer

If your session expires mid-transfer, Blober will prompt you to sign in again. The workflow resumes from where it left off. No files are lost or duplicated.
