If you're using Diskeeper for XPPro, there is an option (in "scheduling" I think) which arranges a Paging File Defrag during the next boot.
In my XP Pro test, it worked for me (not brilliantly, but adequately).

For my XP Home, this doesn't exist, so I don't have that optiion at the moment. I apologise if you've tried that already.

I'm progressing far too slowly here, but I will post if I find some.

In the end, I've already started deleting stuff from my HD and defragmenting afterwards. Bu if I continue this to the bitter end, I'll end up deleting all Windows XP from the HD, which is ht emost brutal, but probably the best way of HD installing Knoppix.
