DROID LeRobot dataset — split tar archive
=========================================

The `droid_lerobot` dataset bundled as ONE uncompressed tar, split into 20 GiB
parts. This avoids transferring ~231k tiny files individually (which overwhelms
the Hub download); instead it's 7 large files.

Contents
--------
  droid_lerobot.tar.part00 .. part06   7 parts, ~130 GB total (last part smaller)
  SHA256SUMS                           sha256 of each part, for integrity check
  README_RECONSTRUCT.txt               this file

Reconstruct (any environment with huggingface_hub installed)
------------------------------------------------------------
  # 1. download all parts
  hf download tturing/transfer --repo-type dataset --local-dir ./droid_transfer
  cd droid_transfer

  # 2. (optional) verify nothing corrupted in transit
  sha256sum -c SHA256SUMS

  # 3. reconstruct the dataset
  mkdir -p /target/droid_lerobot
  cat droid_lerobot.tar.part* | tar -xf - -C /target/droid_lerobot

This recreates data/, videos/, and meta/ under /target/droid_lerobot.

Notes
-----
 - No compression: the payload is already-compressed mp4 video + parquet, so
   compression would cost ~1 hour of CPU for ~1% size reduction.
 - The HuggingFace download cache (.cache/) was intentionally excluded — it is
   local download bookkeeping and is not needed to use the dataset.
 - The source had 4 unfinished (.incomplete) video downloads, so the dataset is
   nearly complete but may be missing a handful of videos.
