PostprocessBuildPlayer scripts do not fire on windows machines to date, and a pre process script for unity does not exist in the public domain, so here is an editor script which adds two custom buttons to your menu:- Custom Build, and Custom Build-Run. The purpose of this script is to allow you to handle any file copying or amendment to the build folder pre or post build automatically.
The script takes all the information required from the normal build window options into account, when executed manually it allows the user to choose a save path, it then fires a pre-process function before building and post process function after building and the build path is sent as a parameter, from within these functions you can call whatever you heart desires from c# file copying code to calling other applications and sending parameters alongside
