A file with VTX extension is a Microsoft Visio drawing template that is saved to disc in XML file format. The template is aimed to provide a file with basic settings that can be used to create multiple Visio files of the same settings. Another similar format is VST which is saved in binary format rather than XML. VTX files are supported with Visio 2010 and newer versions.

Files generated using Visio can also be exported to different file formats such as PNG, BMP, PDF and others.
