It's the index of all the cookies .. I know that seems a bit obvious,
but it is actually true. If you delete it (logged on as someone else -
it's in use when you are logged on) it gets rebuilt all fresh and
squeaky clean, next time the user logs on (using the cookies in the
folder) .. which sort of begs the question why WinXP needs to keep it
around. 8>.

Speed. When you go to a site that asks for its cookie, it is much
easier to look up in the index for the match of its request to an actual
cookie file, than to trawl down all the cookies to find one that matches

Yes, but it can (and does, after you delete it) rebuild index.dat in
<100ms (actually 'so fast I can't measure it'), so why doesn't it just
rebuild it when a user logs on? Keeping a 'permanent' index as well as
objects themselves seems to make no sense, unless indexing is an arduous
task - and in this case it doesn't seem to be (maybe if I had 50k
cookies ..)
