Ghost is designed to be run under DOS and can be run from a DOS boot diskette. Ghost has two modes of operation - menu driven user interface, and a batch mode.
Ghost is essentially a disk-copying program.
The entire contents of a disk may be copied from one disk to a disk image file, and that image file can then be used as a template to create copies of the original disk. Ghost allows the target partition to be expanded or contracted. If the hardware is similar there will be less work after the machine has been cloned. WinNT supports NTFS partitions, as well as FAT partitions, and although Ghost will copy NTFS partitions, it does it on a sector by sector basis. This can cause problems - large disks with only a small amount of data can take a long time to copy, and disk image files can become unacceptably large.
