Partition Saving is a DOS program that is used to save, restore and copy hard-drive, partitions, floppy disk and DOS devices. With this program you could save all data on a partition to a file (such as you could save this file on a CD for example). Then if something goes wrong, you can completely restore the partition from the backup file. You no longer have to reinstall every piece of software from scratch. All you have to do is restore the partition from the backup file and then update any software that was modified since the backup was created.
