How to open a .vdx file
Start with a trusted app that supports this format

What is a .vdx file?
File extension details and usage information
The VDX file format is an XML-based drawing file format used by older versions of Microsoft Visio (specifically Visio 2002, 2003, and 2007). It stores vector graphics, text, and other drawing elements in a structured XML format. VDX files are used to create diagrams, flowcharts, organizational charts, network diagrams, and other types of technical and business drawings. While VDX was a standard format for Visio drawings for a period, it has been superseded by newer formats like VSDX (Visio Drawing) which is based on the Open Packaging Conventions (OPC) and offers improved features and compatibility. Opening VDX files in newer versions of Visio typically involves converting them to the VSDX format. The XML structure of VDX allows for programmatic manipulation and extraction of drawing data, although this is less common than working directly with the Visio application. VDX files are generally larger than their binary counterparts (VSD) due to the verbose nature of XML.

File safety tips
Use caution with unknown files
Only open files from trusted sources. Before opening a .vdx file, scan it with antivirus software, verify that the file extension is expected, and avoid running unknown executable, installer, macro-enabled document, or script files.
