VDX files store cutscenes and videos from The 7th Guest game. They use XML format unlike binary VSD files. VDX diagrams can be viewed without Visio using the Visio Viewer. VDX files are also associated with MS-DOS system drivers. Free online VDX apps allow viewing, editing, converting, merging, splitting, and comparing VDX files without installing anything.
VDX file chunks contain images or 15fps video sequences. Chunks have a type, size, and compressed data. VDX files can convert to AVI videos with the 7th Guest Toolset. Before 2013, Visio drawings saved as VDX or VSD formats. The VSDX format replaced them. So VDX files are less common now. VDX files categorize as data, video, or system files. They support desktop and mobile Windows, Mac and iOS.
