# Extracting Multi-Part Data Exports

This guide provides step-by-step instructions on consolidating and extracting multi-part exported files provided by Rocket.Chat Cloud.

---

### Prerequisites

1. Ensure you have all the `.tar.gz.part` files downloaded to the same directory.
2. Use a Unix-based system (Linux, macOS, or Windows Subsystem for Linux) with standard tools like bash, tar, and gzip installed.

---

### Step-by-step instructions

1. **Verify Checksums** (optional but recommended): Compare the provided checksum file with your downloaded parts using:

```bash
sha256sum files.tar.gz.part*
```

Ensure all parts are intact before proceeding.
2. **Merge File Parts**: Run the following command to combine all parts into a single `.tgz` file:

```bash
for i in {1..N}; do cat files.tar.gz.part$i >> consolidated.tgz; done
```

Replace `N` with the total number of parts you received.
3. **Extract the Consolidated File**:

Extract the `.tgz` file using:

```bash
tar zxvf consolidated.tgz
```
4. **Troubleshooting Extraction Errors**:

If you encounter errors, first check the integrity of the archive using:

```bash
tar zxvf consolidated.tgz
```

If the issue persists, verify the integrity of the consolidated file:

```bash
codegzip -t consolidated.tgz
```

### Common issues and solutions

1. **Checksum Mismatch**: Re-download the affected parts and verify checksums again.
2. **Extraction Fails**:
  - Ensure sufficient disk space is available (at least twice the size of the exported data).
  - Use the `--ignore-zeros` (`-i`) flag if encountering EOF errors.
3. **Missing Tools**: Install the required tools using your system's package manager (e.g., `apt`, `brew`, or `yum`).
