Is it a good idea to occasionally clear out the preftch folder. If so, is it a case of leaving the layout (config settings) and clear the rest, andwhat about the boot folder.Thanks.P.S. My original os xp home.

asdy, Although some third-party applications (such as CCleaner) do this selectively, there are no real performance gains to be had from doing so, and unless you absolutely need the disk space, you can safely trust Windows take to care of things. -Alex
