Virtual CDromX - Version 3.5 Completely and perfectly duplicate CDROM disks and store them on hard disks in the format of VCDROM file (respectively named as FCD file and VCD file). Or sometimes you wish to make your important files scattered in your hard disks into VCDROM so as to keep them from accidental modification(or deletion) and virus infection: make VCDROM from selective files and directories. VcdromX is just the utility that intends to help you build VCDROM files from any directories and any files located anywhere, not simply CDROM disk duplication.
