Check our videoThe 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.
