I ran CCleaner for the first time today, and it's coming up with 146GB of System - Temporary Files. I'm not sure what exactly is causing it, but when I go on detailed results, most of it says After Effects, not sure why. I'm afraid of running cleaner in case it screws something up. It's also showing 80GB of Internet Explorer - Temporary Internet Files, and that seems like a lot of websites cached or something.
Please tell me whether or not I should just run the clean. It would free about a third of my total used space, 931GB, 349 used, 152 to clean, which would leave like 200GB used.
