Bulk Uploads via Drag-and-Drop

For uploads of more than a handful of files, drag-and-drop is fastest. Papyrus accepts whole folders preserving their sub-folder structure.

How

1. Open Documents in the left navigation
2. Drag a folder from your desktop / file explorer
3. Drop it anywhere on the page
4. Configure: destination folder, default classification, tags
5. Click Start upload

A progress panel appears showing each file's status. You can navigate elsewhere — the upload continues in the background.

What happens during a bulk upload

For each file:

1. SHA-256 hash computed locally
2. Hash sent to server (duplicate check — skip if already exists)
3. File uploaded
4. AI classification + extraction runs
5. Document appears in the destination folder

Documents appear one by one as they finish processing. The order isn't guaranteed (some classify faster than others).

Sub-folder preservation

If your dropped folder has sub-folders, Papyrus mirrors the structure:

Dragged folder: 2026 Q1 Records/
  ├── Invoices/
  │   ├── jan/*.pdf
  │   └── feb/*.pdf
  └── Receipts/
      └── *.pdf

Becomes in Papyrus:

Your destination folder/
  └── 2026 Q1 Records/
      ├── Invoices/
      └── Receipts/

Sub-folder names also become tags automatically: 2026-q1-records, invoices, jan, feb, receipts.

File size and batch limits

If a batch exceeds the limit, the upload starts but stops at the threshold. You'll see which files were uploaded.

Resumable behaviour

If your browser crashes or network drops mid-upload, the queue persists in your browser's local storage. When you return to Papyrus, you'll be offered “resume upload” with the remaining files.

For very large bulk uploads (10,000+ files), the Desktop Agent is faster than the browser — it has better local persistence and parallelism.

What to do with duplicates

When Papyrus detects a duplicate (same SHA-256), three choices:

• Skip: file isn't uploaded again
• New version: this file becomes a new version of the existing document
• Keep both: both stored as separate documents (the new one gets a (2) suffix in title)

For bulk uploads, you set the default at the start. You can override per-file from the progress panel.
