VxD

VxD designates a virtual device drivers for the Microsoft Windows operating system. " VxD " stands for "virtual driver x ", where "x " in the acronym was originally intended to stand for a hardware component "d " stands for example for display, so display devices. "c" would have for communication, "p" for printer and confessed " n" for network. Thus, a file with the extension " VPD " would be a virtual printer driver. Since the "x" was often not replaced in the shortcut through a different letter, you will find usually only files with the extension ". VXD ". The drivers have the file extension .386 under Windows 3.x and Windows 95 vxd It should be noted that the .386 -. Files can also be used under Windows 95, but not vice versa. This virtual device driver controls the system resources such as hardware (printer, internal controller, plug-in cards, etc.) or installed software ( eg anti-virus software AntiVir ). For example, several applications can access the same resource. With the introduction of Windows Driver Model Windows 98 VxD were unnecessary, but it could still be used until Windows ME. Windows NT and derived therefrom systems do not support VxD 's more.

The VxD should not be confused with the NTVDM specific " VDD " (Virtual Device Drivers ).
