I built this PC last year around this time and I never had this issue until now. Yesterday my 250GB SSD space was 110 GB free. Today I checked my space and it was 14.2 GB free. I checked all my folders in the SSD and it seems to be in my "User" folder, under my user. I look through it and there is about 20GB in the folder, but when I go to the User folder and check the properties it shows 97GB... I don't know where this space is!!!!
