Oh, they can. They simply open the image and drill down into the
filesystem, then extract the single file. Ghost has had this
functionality for years (using Ghost Explorer).

Not true either, Acronis brings in a special driver to take care of that
(I assume it works a little like St Bernard's Open File Manager).
For the reasons I already mentioned (metadata catalog, ...), I still
wouldn't consider disk imagers as good backup solution though. They're
invaluable when doing complete system restores but I still doubt their
ability to wrangle files or directories like todays backup systems can.
