For unzipping the multipart dataset MGO12 you can either use the `7z` command

```bash
7z x MGO12_freemovement_long_session.zip
```

Or, the `unzip` command, but since it doesn't support multipart files, you will need create an intermediary file with `zip` like this:

```bash
zip -F MGO12_freemovement_long_session.zip --out MGO12.zip
unzip MGO12.zip
```
