Ghost Host - Version 1.0 It uses the only way to "hides" files so they cannot be seen with ANY type of directory command or file search. It is not a "hidden file" flag that can be overcome by the show all option. The only way to find a file hidden with Ghost Host is to use an exhaustive file-content search utility that reads all files on the disk and looks for specific strings (usually only works with ASCII type files). Ghost Host hides any file type behind many common file types, such as *.wpd, *.doc, *.bmp.
