VSTX files belong to Vector Image Files category, along with 138 other formats. Microsoft Visio, created by Microsoft Corporation, is the most used program for working with VSTX files. VSTX file format is based on XML specifications of OpenOffice unlike older .VST binary format. VSTX inherits XML structures from Visio XML Drawing format (.vdx).
VSTX files store diagram templates for Microsoft Visio 2013. They are used to create multiple Visio drawings (.VSDX files) with similar appearance. Microsoft introduced VSTX format when releasing Visio 2013. Previous Visio versions use .VTX for templates instead.
To open unknown VSTX files, update application used to open them. Only latest software versions support current VSTX format. Also scan VSTX files with antivirus to check for viruses before opening. The most common VSTX-compatible program is Microsoft Visio.
