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. On most operating systems the name text file refers to file format that allows only plain text content with very little formatting (e.g., no bold or italic types). Such files can be viewed and edited on text terminals or in simple text editors.
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. "Text file" refers to a type of container, while plain text refers to a type of content. Text files can contain plain text, but they are not limited to such. At a generic level of description, there are two kinds of computer files: text files and binary files.
