The stuff in this folder is taking up so much space thats i'm running out of disc space. Is it safe to empty? ---update--- Apparently it is safe to delete. I deleted that folder a day ago with no real issues. The system just recreates the folder and starts filling it up again. It's not a permanent solution but atleast I know how to get my space back. ---update--- Hazaaa! I found the problem or at the very least the source of those files. That folder has to do with Comcast. I watch tv online and it's comcast's website that is filling up that folder with tons of stuff. I had the folder open and noticed that I had no new files then I started watching online tv and immediately safari started writing to that folder.
