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.
The ODT format is an open standard file format for word processing documents, developed by the Organization for the Advancement of Structured Information Standards (OASIS). It is supported by various applications, including LibreOffice, Apache OpenOffice, and Microsoft Word (with compatibility plugins), making it a versatile choice for cross-platform document creation and editing. The format is based on XML and ZIP compression, allowing for structured data storage, support for advanced features like styles, metadata, and embedded objects, and ensuring interoperability across different software environments.
You can also convert CHM into many other file formats. Please see the complete list below.
