techidave: FARR is only really meant to index a relatively small amount of folders (like start menu, program files folder, and perhaps your "my documents" folder), since in the current versions it will always re-scan all the folders every time you search. This works OK most of the time because of windows filesystem caching, but still...
You really ought to check out
locate32. It works by indexing your drives (which is pretty fast), and afterwards it can
find locate things more or less instantaneously. REALLY good stuff.
