Open VDM File

A VDM extension file is nothing more than a source code of a program based on the Vienna Development Method, or VDM according to its acronym, which is a set of techniques for modeling computer systems.

What is the Vienna Development Method?

The Vienna Development Method, or VDM is one of the oldest formal methods for developing computer systems.

Created by work done at the IBM Laboratory in Vienna in the 1970s, it has grown to include a group of techniques and tools based on a formal specification language: the VDM Specification Language (VDM-SL).

It also has an extended form, VDM++, which supports object-oriented modeling and concurrent systems.

Support for VDM includes commercial and academic tools for analyzing models, including support for testing and proving model properties and generating program code from validated VDM models.

There is a history of industrial use of VDM and its tools and a growing body of research on the formalism has led to notable contributions to critical systems engineering, compilers, concurrent systems, and in logic for computer science.

That said, the VDM extension file, then, contains code written in VDM-SL, the VDM Specification Language, or VDM++.

How Can I Open VDM File on Android

If you downloaded a VDM file on Android device you can open it by following steps below:

In the Android apps list on your Android device find "My Files" or "File manager" app and tap to start it.
Tap on "Downloads" folder inside the app.
You should see your downloaded VDM file in that folder.
Tap on the file. If Android device supports opening the file you downloaded it will open in the corresponding app.
If file does not open you can look for the corresponding app that can open the file by searching Android App Store for the "VDM".
If you cannot open the file with the apps from Android App Store it is possible that the file could only be opened on desktop platforms such as Windows or Mac OS. Try searching for "VDM viewer", "VDM file reader" online and see if any desktop applications can open it.
It is also possible that the file you downloaded is outdated and is no longer supported.

How to Open VDM File on iPhone or iPad
