vDos derived from the DOSBox project (http://sourceforge.net/projects/dosbox/).

DOSBox is targeted at gaming and available for many operating systems.
If you consider using it for a database application. DON’T, mostly you’ll end up with corrupted data.

vDos is for serious (mainly text mode) DOS applications, Windows 32/64 bits (XP and later) only.
It lacks many of the hardware emulations of DOSBox (no joysticks, basic VGA...).
Instead it adds a live file system, file/record locking, Windows printing, a scalable screen font and more.
You should be able to run your DOS application quickly in a safe and convenient way.

    A remarkable project, letting users run MS-DOS apps very effectively under Microsoft Windows (32- or 64-bit) from XP right up through Windows 10, with gorgeous full-screen displays and your choice of TrueType fonts. I'm getting great performance out of WordStar for DOS, including clipboard support and using modern printers. Thank you, Jos Schaars!

    Wow. I support a few creaky old Clipper apps, some of which were written in 1992 or so. I'm now compiling and running a Clipper app on my Win 8.1 laptop no problem using vDos. Impressive.

    Incredibly easy to install and configure. Since most of the gaming-specific stuff has been removed, it's MUCH faster and more stable for running business apps than standard DOSBox (for example, re-indexing a 225MB cTree data file went from taking approximately 3 hours to just over 20 minutes - on the same hardware). I had previously been struggling with another DOSBox customization (0.73MB with file/record locking); even with "cpu=max", it was incredibly slow and not very stable. So far, vDOS is darn fast and appears to be rock-stable. It even warns the user if s/he tries to kill vDOS while the app is still open. Thanks to vDOS, my clients just might be able to keep their ancient software for another few years! As I always say: if it ain't Baroque, don't fix it. Hartelijk dank, Jos!

    This mod of DosBox has been sorely needed in the business community since the demise of WinXP. The install was pretty easy. The self-documentation in the autoexec and config files was very helpful. Most importantly, I got my dos-based Cobol programs running; no changes required. I test-installed this on a Dell mini laptop running Win 7 Starter. Function keys were a problem with every program that used them (none in my Cobol code, though); maybe that's a function of its being a notebook. One of my really old dos programs, an extremely simple file viewer, wouldn't run and Microsoft's EDIT and QBASIC wouldn't work. So it's not totally perfect. This virtualization of DOS works so well with Windows since all the files are accessible in Windows folders. The dos window can be either a scaled window or full screen. The character-based display is crystal clear. The reference to the columbia.edu site is an excellent one, incidentally. I haven't experimented yet with printing. It almost looks too good to be true if I can actually print my PCL-based forms!

    Excellent to run Old DBASE programs that need locking files!
