Uploading Files
Add documents, images, and archives to bervice with end-to-end encryption. Files are chunked, encrypted locally, then synced securely. This guide covers methods, limits, performance tips, and troubleshooting.
Drag & Drop
- Open a Space (e.g., Work).
- Drag files/folders into the window.
- Add title, tags, and notes (optional) → Upload.
Best for quick, ad-hoc uploads.
New → File
- Click New → File.
- Select one or many files.
- Review queue → Start.
See progress, pause, or cancel per item.
Browser Extension
- Right-click images/PDFs → Save to bervice
- Attach a file directly to an existing item
Requires unlocked desktop app. See Browser Extensions.
How Uploads Work (Security)
- Files are split into chunks and encrypted locally (AEAD per chunk).
- Only ciphertext + integrity tags are sent; keys never leave your device.
- Resume support: interrupted uploads continue from the last verified chunk.
File Sizes
- Recommended per file: up to 5–10 GB
- Batch very large sets into 2–5 GB groups
- Archive folders to .zip/.tar before upload
Performance Tips
- Keep 2–5 GB free disk space for cache
- Prefer wired or stable Wi-Fi; avoid sleep
- Throttle concurrency in Settings → Performance
Organization
- Upload into the correct Space/Vault
- Add tags (
#legal,#design) and owner - Attach files to related items for context
Upload Queue Controls
- Pause/resume per file or entire queue
- Reorder to prioritize critical documents
- Open logs for detailed transfer diagnostics
Integrity & Verification
- Checksums displayed after upload
- Integrity check re-verifies chunks on demand
- Corrupted blocks are re-fetched automatically
Sharing After Upload
- Move to a Team Space to share with roles
- Use Viewer for read-only, Can edit for maintainers
- Revoke by removing from the shared space
Only the file key is re-wrapped to recipients—never your master key.
Versioning
- Re-uploading creates a new version
- Add change notes to explain updates
- Restore or download any previous version
Troubleshooting
- Upload stuck: Toggle Sync off/on; try another network.
- “File too large”: Split into smaller archives; upload sequentially.
- Slow transfers: Reduce concurrency; exclude cache from aggressive AV.
- Integrity error: Run Integrity check to re-verify chunks.
- Preview fails: Download and open in a native viewer.
