vDos is a utility application fromJHM Schaars. This free app works as a DOS emulator, replacing Windows' NTVDM technology. It allows you to run DOS applications on modern computers. It loads the DOS software on its own window and comes with network and printer support. It also provides other features, such as clipboard access and direct access to your system files.

Unlike DOSBox, however, vDos is not targeted at gaming. It is mainly for text mode DOS applications. Users must also note that the emulator lacks many of the hardware emulations of DOSBox, such as a joystick and basic VGA. 

What is vDos?

If you attempted to run DOS programs—and even older programs—on Windows computers, chances are you experienced getting an error message. This is because DOS applications cannot be run in a Windows environment. You require an emulator that can mimic the functions of the MS-DOS systems. Lucky for you, there are various DOS emulators available nowadays. One of those is vDos.

It’s a lightweight utility that enables you to load and run DOS software on Windows. It lets you use variables, although you must explicitly declare them via autoexact.txt, command line, or another batch file. You can also use Command Point, but you should know that it's linked to the Windows CMD. With this, provide the program with quotes and specify the command from within a program or command line.

The tool lets you run multiple programs simultaneously. Even better, they can run with specific configurations without creating conflicts or errors with other Windows NTVDM instances running on your system. Moreover, it comes with network and print support. However, vDos is mainly for text mode DOS applications only. It is not recommended for DOS games as it lacks many hardware emulations, such as a joystick and basic VGA.

Should you use it?

Overall, vDos is a must-have if you wish to go old school and run DOS applications. This emulator mimics the functions of the MS-DOS system, allowing you to run old DOS applications on your modern Windows computer. However, doing so requires knowledge as there are many parameters involved. Additionally, it can only run text mode apps. It is not designed to run old DOS games.
