CHM

Microsoft Compiled HTML

The CHM file format was developed by Microsoft for storing and displaying online help documentation, combining multiple HTML pages into a single compressed file. It is commonly opened using Microsoft's HTML Help Viewer, but third-party tools like 7-Zip or SumatraPDF can also extract or view CHM files. The format supports a hierarchical table of contents, full-text search, and embedded multimedia, making it a versatile solution for organizing and accessing help content efficiently.

EPUB

Digital E-Book File Format

EPUB (Open eBook File) is a widely used open-standard file format for digital books and publications, designed to be flexible and accessible across various devices. It is supported by most e-readers, such as Kindle, Apple Books, and Adobe Digital Editions, as well as software tools like Calibre for creating and managing EPUB files. The format is based on HTML, CSS, and XML, allowing for reflowable content, embedded fonts, multimedia support, and advanced features like annotations, bookmarks, and accessibility options for visually impaired readers.
