dos skills are easy to reclaim
an easy setup for a batch would be like:
%sysdrivewherecacheis% ie: C:
cd [folder where cache is] ie: cd Progra~1 ("Program Files" but some dos based os's cant read more than 8 chars, unlike 2k)
del *.*
(or you can refine by typing something like del *.gif or *.html)
and then if you wanna do more folders
just add something like this:
cd.. (knocks the tree back one, from C:\Progra~1\ to C:\ )
cd Temp
del *.*
and just name it something.bat
(make sure file extension is bat and not txt though :P)
you could get way more intense with some scripting but i prefer to keep my scipting to perl and php

but i think youd benifit from geting xteq, its amazing, i dont leave home without it.
