Format introduction
Microsoft Compiled HTML Help is a Microsoft proprietary online help format, consisting of a collection of HTML pages, an index and other navigation tools. The files are compressed and deployed in a binary format with the extension .CHM, for Compiled HTML. The format is often used for software documentation.
The Rich Text Format (often abbreviated RTF) is a proprietary document file format with published specification developed by Microsoft Corporation for cross-platform document interchange with Microsoft products. Most word processors are able to read and write some versions of RTF.
Technical details
Help is delivered as a binary file with the .chm extension. It contains a set of HTML files, a hyperlinked table of contents, and an index file. The file format has been reverse-engineered and documentation of it is freely available. CHM files support the following features: data compression, built-in search engine, ability to merge multiple .chm help files, extended character support.
Unlike many word processing formats, RTF code can be human-readable: when an RTF file is viewed as a plain text file, the contained ASCII text is legible. The formatting code is not too distracting nor counter-intuitive, provided that the document's creator kept formatting concise.
