AWindows automatically hides some files and folders which are mostly system and settings to stop novice users accidentally mucking about with their system......The files your refering to are most likely bits left over from programs installing themselves onto your PC....anything in your temporary folder that hasn't been accessed for a week or so is usually safe to delete BUT as always when making changes like this your best and safest bet is to do a back up or create a restore point on XP so you have a safety net should things go belly up.
