SECTION / 01

Confirmed archive handling

The current pipeline accepts one local directory or ZIP file, inventories entries and preserves the source. Common photography archives may include JPEG/JPG, Nikon NEF and NRW, TIFF, PNG, MOV and MP4. Actual behaviour still depends on file structure and available decoders.

  • Open one downloaded ZIP file or one extracted folder
  • Progressive local inventory and issue review
  • Exact duplicate-content detection
  • Non-destructive organisation preview
  • Copy to a destination selected by the user
  • Destination presence, size and SHA-256 verification

SECTION / 02

Recognition

Recognition classifies a file or archive entry so it appears in inventory. It is not a promise that every preview, codec or proprietary field can be decoded.

SECTION / 03

Metadata extraction

Available capture dates, dimensions, camera and lens information, exposure details and GPS information can be read where present. Missing fields are treated as missing, not corruption.

SECTION / 04

Preview support

A thumbnail is a convenience for review, not the preservation test. RAW and video preview availability may depend on embedded previews or supported local decoders.

SECTION / 05

Verification is format-independent

Presence, size and SHA-256 comparison can verify the expected copy without interpreting the photograph. A green VERIFIED state appears only when every expected destination item passes.
