Automatic Copying of Release Executables to a Specific Folder on a Successful Build

I have a couple of apps that I use on my desktop and my Surface - and it's a pain when I change them, as I always forget to update the Surface to run the latest EXE. So I figured I'd add a post-build step to Visual Studio to automate a copy of Release (and Release only) files (the EXE and all its related / supporting DLLs) to my NAS for easy access. Turns out it's not that trivial.
