The Branton Files are a series of documents espousing various conspiracy theories. They have circulated on the internet since at least the mid-1990s. They are named after their editor, Bruce Alan Walton. The UFO conspiracy theory is prominently featured, but many other conspiratorial ideas are also mentioned. Many wild claims are made and are presented as self-evident, but little in the way of coroborative evidence is offered. The Branton Files might be seen as elaborate urban legends.
