Editing Ghost (disk utility) (section)

=== GHOST 4.0 and 4.1 ===
Version 4.0 of GHOST added [[multicast]] technology, following the lead of a competitor, [[ImageCast]]<!-- New article needed -->. 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. This version also introduced GHOST Explorer, a [[Microsoft Windows|Windows]] program which supports browsing the contents of a disk image file<!-- can't find article --> and extracting individual files from it. Explorer was subsequently enhanced to support adding and deleting files in a [[File Allocation Table|FAT]]-formatted image, and later with [[ext2|EXT2]], [[ext3|EXT3]] and [[NTFS]] [[file system]]s. Until 2007, GHOST Explorer could not edit NTFS images<!-- directly contradicts previous sentence -->. GHOST Explorer could work with images from older versions but only slowly; version 4 images contain indexes to find files rapidly.

Version 4.0 also moved from [[real mode|real-mode]] [[DOS]] to [[80286|286]] [[protected mode]] via [[Phar Lap Software|Pharlap Extender]].<ref name=Dassow/> The additional memory available allows GHOST to provide several levels of [[data compression|compression]] for images, and to provide the file browser. In 1998, GHOST 4.1 supports password-protected images. This version dropped OS/2 support.<ref name=Dassow/>
