can somebody please tell me whats going on

i have never seen this before

i am running windows 7 WAMP

Thank You

Looks like you have some sort of caching enabled somewhere within CI, and it's set to write to that dir. Check whether you have cache_on enabled in your db config, and also what location cachedir is set to. Default is empty string, which could very well be the root dir of your site.

That was it... spot on.. thanks for your help
