I'll explain the problem for him... searching in windows has been completely useless since windows 2000. XP, Vista and 7 are all one big balls-up in terms of searching ability. Every iteration is different, but just as broken and the one before. I did a
search for 'shadercache' and got some files that i didn't want, then i searched for 'global' and got a loads of files named 'globalshadercache*' which are the ones i wanted. I uploaded these two images to demonstrate the problem...

Can I say WTF any louder micosoft? Could you get someone who isn't 14 years old and retarded to actually come along and fix this BS? Ive been living with it for too many years now.
