VSSX

Visio Stencil File Format

The VSSX file format is a Visio Stencil file used by Microsoft Visio to store collections of shapes, symbols, and templates for creating diagrams. It is primarily supported by Microsoft Visio and can also be opened with compatible diagramming tools like LibreOffice Draw or online converters. The format is XML-based, allowing for structured data storage, and supports advanced features like shape customization, metadata, and reusable components for efficient diagram creation.

MHT

MIME Encapsulation of Aggregate HTML

MHT is a file format used to save web pages as a single file, combining HTML, images, CSS, and other resources into one archive for easy storage and sharing. It is supported by web browsers like Internet Explorer and Microsoft Edge, as well as tools like Microsoft Word and specialized MHT viewers or converters. The format uses a MIME structure to embed all web page elements, including text and binary data, into a single file, often encoded in Base64, enabling offline access and preservation of web content.
