I have multiple hard drives, 4 of them. 2xSSD's and 2x Mechanical. My boot drive is 120Gb and is filling up without me adding anything to it. All my programs are installed on my second SSD, my download folder is on a mechanical drive. I have all my directories for downloads on a different drive than my boot. Even though I have tried to get nothing to install on it, I have gone from 8.5Gb this morning to 0Mb by 10:30 tonight. I haven't even downloaded anything today. I have already taken space saving measures, such as compressing everything and setting the System protection thing to 5%, there are no programs or files I can remove from the drive, what do I do?
