The GHO file extension is associated with Norton Ghost. Norton Ghost 2003 and earlier versions of Norton Ghost create backup images in GHO file format. Norton Ghost 12.0, Norton Ghost 14.0, and Norton Save & Restore 2.0 do not support GHO file format. Norton Ghost 9.0 and later versions create backup images in the .v2i file format. You cannot restore the .gho image files using these products. However, you can use the Ghost Explorer to restore the individual files and folders from the .gho file.
