Review comment:
The `rename` API returns a boolean. `true` if rename was successful and in
`false` in some cases. For instance, if the parent directory is not present in
`newLocation` then `rename` will return a `false` instead of throwing an
exception. Example:
```
rename `/a/b/c/x` to `/a/b/d/x` will return `false` if `d` does not exist.
