FILE FORMAT GUIDE
What is a VDX file?
An XML-based Microsoft Visio interchange format used by older Visio releases. Use this guide to decide whether to keep VDX or convert it for a different workflow.
PRACTICAL OVERVIEW
Where VDX works well
VDX is a strong choice for recovering structured legacy diagrams without the original Visio application.
The right output depends on what must remain editable, how the file will be shared, and which application or device needs to open it.
FORMAT QUESTIONS
About VDX files
What is VDX best used for?
VDX works especially well for recovering structured legacy diagrams without the original Visio application.
What can change during conversion?
Connectors, custom masters, text layout, and application-specific properties may change. Features that do not exist in the chosen output format cannot be carried across exactly.
Should I keep the original VDX file?
Yes. Keep the original until you have opened the result and checked its layout, quality, data, media tracks, or other important details.
