🔸 Description 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 MOBI file extension was created in 2000 by Mobipocket. This company produced Mobipocket Reader applications for computers and smartphones. In 2005, Amazon bought Mobipocket. As a result, MOBI files are identical to Amazon's AZW format for Kindle devices.
🔸 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. In addition, CHM files support the following features: data compression, built-in search engine, ability to merge multiple .chm help files, extended character support. The Mobipocket ebook format is based on the Open eBook standard using XHTML and can include JavaScript and frames. It also supports native SQL queries to be used with embedded databases. The Amazon Kindle's AZW format is just the Mobipocket format with a slightly different serial number scheme, and .prc publications can be read directly on the Kindle. The Kindle AZW format also lacks some Mobipocket features such as JavaScript.
