Support via chat and knowledge base was available until June 30, 2014. Norton Ghost was discontinued on April 30, 2013. In 1998, Ghost 4.1 supports password-protected images. The additional memory available allows Ghost to provide several levels of compression for images, and to provide the file browser. Version 4.0 also moved from real-modeDOS to 286protected mode.
Ghost Explorer could work with images from older versions but only slowly version 4 images contain indexes to find files rapidly. Until 2007, Ghost Explorer could not edit NTFS images. Explorer was subsequently enhanced to support adding and deleting files in an image with FAT, and later with ext2, ext3 and NTFSfile systems. This version also introduced Ghost Explorer, a Windows program which supports browsing the contents of an image file and extract individual files from it. Multicasting supports sending a single backup image simultaneously to other machines without putting greater stress on the network than by sending an image to a single machine. Version 4.0 of Ghost added multicast technology, following the lead of a competitor, ImageCast.
