Termed as Driver for Virtual CD-ROMs, the vcdrom.sys file is a driver process that runs in Windows computer, and a component of the program Virtual CD-ROM Device Driver, which is a product created by Microsoft Corporation for computers that are pre-installed with Microsoft Windows Operating System. Also called VCDROM, Virtual CD-ROM Device Driver is a type of software that enables audio and data support for all compatible CD-ROM programs that are running in MS-DOS. It features two main things, which are required to support MS-DOS CD-ROM applications. Among those features is that the virtual device driver, which refers to vcdrom.sys, is used to emulate MSCDEX by giving the services that all CD-ROM programs need for their installation. Therefore, the vcdrom.sys file is an essential component for the installation of CD-ROM applications when using Virtual CD-ROM Device Driver. It is considered as its core component that makes the driver software work.
