GHO (Norton Ghost Backup File)
The GHO Misc file format
Norton Ghost backup files are commonly saved using the GHO file extension. These files are used to create an exact copy of a hard drive or whole device. This copy is used as a full backup of the hard drive. The program formerly known as Norton Ghost has been renamed to Ghost Solution Suite which contains the same functionalities.
Technical details of GHO files
GHO files contain all data from a hard drive or device as an exact copy. This allows users to restore either individual files or a complete hard drive or device's content. The copies of a device are saved as some kind of image file format. Since it is limited to the maximum DOS file size of 2 GB, bigger files are split into smaller files that each do not exceed the file size of 2 GB.
