# Restore the original archive files

The repository is being uploaded. Each original listed in `manifests/` has a complete set of binary pieces. Other originals may still be pending.

Download the pieces, `manifests/`, and `restore_archives.py` to one directory. Once your access request has been approved and you have logged in to Hugging Face:

```bash
hf download lanhe1124/archives --repo-type dataset --local-dir archives
cd archives
python3 restore_archives.py
```

To restore just one available original:

```bash
python3 restore_archives.py --file gcd_kubric4d_test.tar.gz
```

The script verifies every piece's size and SHA-256, concatenates pieces in manifest order, and verifies the complete original SHA-256. It never overwrites an existing original or deletes pieces. Restoration requires additional free space equal to the original size. It does not decompress archives.

To write restored files elsewhere, add `--output /path/to/output`. After a failed or interrupted attempt, inspect and remove only its `.restoring` output before restarting; existing completed originals are preserved.

The training originals named `.aa` through `.ar` are themselves volumes of the original training archive. Restoring their `.partNNN` pieces reproduces those original volumes byte for byte.
