# Robotics split tar archives

This folder contains split `tar` archives for several dataset directories.

## Naming

For a dataset named `<NAME>`, the parts are:

- `<NAME>.tar.part0000`, `<NAME>.tar.part0001`, ...

Example: `kitchen.tar.part0000`, `kitchen.tar.part0001`, ...

## Extract

Choose an output directory (called `TARGET_DIR` below). Extraction creates one top-level folder, e.g. `TARGET_DIR/kitchen/...`.

Extract one dataset:

```bash
mkdir -p TARGET_DIR
cat kitchen.tar.part* | tar -xf - -C TARGET_DIR
```

Extract multiple datasets:

```bash
mkdir -p TARGET_DIR
for name in kitchen living general mobile study; do
  cat "${name}.tar.part"* | tar -xf - -C TARGET_DIR
done
```

## Troubleshooting

- `tar: Unexpected EOF` usually means a part file is missing or incomplete; re-copy the missing part(s) and retry.
- Keep all `*.tar.part*` files in the same directory when running `cat`.
