Fails silently when deleteing a non-empty folder on Windows

[bicarlsen]

On Windows, it seems the delete function does not delete a directory if it has contents, but will return Ok. Is this intended behavior? If so, would it be worth adding a delete_recursive convenience function so users don't have to manually walk the directory tree?

Thanks for bringing this up.

When looking at the documentation of delete() it's not entirely clear what should happen when a directory is encountered. It's likely that 'single' means 'empty' in case of a directory. This could be validated by looking at the tests, and then an improvement should be made to the docs to clarify.

Based on that outcome, a delete_recursive() function might be needed to handle this case more conveniently.
