I have tried other solutions that seemed to work for people with the same problem but none have helped so far. I was able to see with TreeSize that my C drive, which has randomly been filling up over the past few months even though I have downloaded nothing, has 150GB of space taken up by the System Volume Information folder. When I open this the files taking up the space are not under a specific category. I have tried to remove these files because everyone has told me they are old restore points but when I go through this process nothing is deleted. Any suggestions? Thanks in advance
