Addresses issue #285

Thanks for this PR @troggy, but we shouldn't be using File.join since the separator isn't guaranteed to be the same across environments. Can you refactor to use vanilla string concatenation instead?

@c0mrade - between you and @troggy , whoever gets me a PR for this (without the File.join and preferably with a test) wins! =]
