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.

OTP

Origin Graph Template

The OTP (OpenDocument Presentation Template) file format is a standardized template format used for creating presentations within the OpenDocument family of file formats, maintained by the Organization for the Advancement of Structured Information Standards (OASIS). It is primarily supported by open-source office suites like LibreOffice and Apache OpenOffice, as well as other applications that adhere to the OpenDocument standard. The format is based on XML and supports advanced features such as embedded multimedia, customizable slide layouts, and compatibility with other presentation formats like PPT and PPTX through conversion tools.
