What is a VSTM file?
The VSTM format acts as a macro-enabled template for Microsoft Visio, utilizing the OPC/XML architecture to define document baselines, styles, and settings alongside executable VBA macros. It is structurally identical to the VSDM drawing format but causes Visio to instantiate a new, untitled .vsdm or .vsdx file upon opening rather than editing the template itself. This format is critical for automated diagramming workflows relying on scripting.
How to open a VSTM file
Microsoft Visio is the only software capable of fully utilizing VSTM files, specifically for executing the embedded macros and preserving template behaviors. Third-party viewers like ConceptDraw PRO may render the static vector content, but the dynamic scripting elements and template instantiation logic are proprietary to the Microsoft Office ecosystem.
