VSTX

Microsoft Visio File Format

The VSTX file format is a template file used by Microsoft Visio, a diagramming and vector graphics application, to store predefined settings, layouts, and shapes for creating diagrams. It is primarily used with Microsoft Visio but can also be opened by other diagramming tools like Lucidchart or LibreOffice Draw with limited compatibility. The format is based on the Open Packaging Conventions (OPC) and stores XML-based data, enabling advanced features such as custom stencils, themes, and reusable templates for streamlined diagram creation.

MHTML

MIME Encapsulation of Aggregate HTML

MHTML (MIME HTML) is a web page archive format that combines HTML, images, scripts, and other resources into a single file for easy storage and sharing. It is supported by web browsers like Microsoft Edge and Internet Explorer, as well as tools such as email clients and web development software. The format uses MIME encoding to embed external resources directly into the file, enabling self-contained web pages with advanced features like CSS, JavaScript, and multimedia elements.
