Files with .vstx extensions are drawing template files created with Microsoft Visio 2013 and above. These VSTX files provide starting point for creating Visio drawings, saved as .VSDX files, with default layout and settings.
Developed by Visio, a business diagram program, VSD files store drawing projects. The files contain texts, visual objects, information flows, or imported data sources details.
