What are virtual disks?
Virtual disks are the disk partitions of virtual machines. They are stored as files on the file system of your host operating system. One of the key features of VMware Workstation is encapsulation. This means that complete environments are contained in a set of files, which can be copied, moved, and accessed quickly and easily. Since an entire disk partition is saved as a file, virtual disks are easy to back up, move, and copy. You can create virtual SCSI and IDE disks as large as 950GB.
