Fonts in Vista

(No response to this on the .printingfonts newsgroup, perhaps more
luck here...)

Can anyone please explain to me:
(i) Why the names of some of the fonts in MS-Word and other apps
begin with "@" but the Fonts folder in \Windows has no file with the
same name;
(ii) Why some fonts cannot be deleted from the \Windows folder,
although they don't seem to be particularly essential to Windows
(e.g. batang, dotum, gulim,...);
(iii) If there is a better freeware utility than AMP Font Viewer for
managing collections and uninstalling unwanted fonts in Vista. I
keep having probs with this despite installing in a non-system area!
