Hey forum! I recently made the switch from Windows to Mac. A whole new world, and a much faster and neater interface too. Anyway here's my problem, I can't seem to delete a ppt file which I downloaded from my school system on the internet. There is a screenshot which I attached together with this post. The file is BESIDE the Cognitive folder. Please help! I know I'm posting a minor problem, but I tried searching for this and I can't find any solutions!
