How to include Local htm pages in a Tampermonkey script?

Question

The script below works on a normal webpage, but how I can make it work on local .htm files too? (When opened in the Chrome browser)

// ==UserScript==
// @name            betterTwitter
// @version         0.5
// @namespace       http://www.h4xful.net/
// @description     Gets rid of the garbage on Twitter's side-panel.
// @include         http://twitter.com/*
// @include         https://twitter.com/*
// @include         file://C:/Users/*.htm
... ... 

The last line (@include file:...) doesn't work at all. The script doesn't fire for a sample page.

Answer 1

First, on Chrome's extensions setting page (chrome://extensions/), make sure Tampermonkey has access to file URLs:

Second, format the @include (or @match) with the correct number of slashes. It should almost always start with file:///.
For example:

// @include    file:///C:/Users/*.htm
