A simple bit of extension methods that lets you write "someFolder" / "otherFolder" / "LastFolder" to create a java.io.File with that kind of path. An important feature of this, is that it's completely OS agnostic, meaning you don't have to worry about it being \ in Windows and / in Unix-based OSs, you just write it, and it handles the rest from …
