This is the source code of byenow, a multithreaded folder removal utility for Windows.
The code is shared to allow anyone interested to see how exactly the program works. The source is incomplete, because it depends on several libraries that are not a part of this distribution. However, with an exception of simple_work_queue, these libraries are simple Win32 API wrappers and their functionality should be fairly obvious from their usage.
To read through the code, start with wmain_app() in byenow.cpp and go from there.
