We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
download_only w/path fails to use path argument when checking for file
When `download_only` checks to see if the file already exists before copying it, it ignores the path argument. This means that:

```
retriever download MoM2003 -p testdata
```

will keep overwriting the file in `testdata` if it exists, and it will not copy the file to `testdata` if the file exists in `.`.

Fixes this is probably just a little logic improvement in the `final_cleanup` function of `download_only`.
