Short for CD-ROM File System, the Windows 95 driver for CD-ROM players. CDFS replaces MSCDEX, which was used for DOS and Windows 3.x systems. Unlike MSCDEX, which is a 16-bit program that runs only in real mode, CDFS is a 32-bit program that runs in protected mode. In addition, it uses the VCACHE driver to control the CD-ROM disk cache, which results in much smoother playback.
