.chm is a windows online help file. It stands for Compiled HTML Fiile and is basically a set of html pages joined together, with the menus as a set of hyperlinks. I would think there is native support for them with any Windows box, but don't quote me. I checked and it says the file is opened by Microsoft HTML Help Executable, whatever that is. The nice thing is you can take any set of html pages and join them together with a chm editor rather than having a complicated directory structure like you often see with older e-books.
Firefox has a chm reader addon, apparently.
