For months, Windows 10 complained that it didn’t have enough space on the hard disk, but the options it gave me to clean up space were ridiculous. Worse, the “storage” function that supposedly tells you what’s taking space wasn’t even close to the truth. This became so bad that I was forced to remove some things I didn’t want to remove, often with a lot of effort, because space was so tight that Windows didn’t even have enough to run the uninstaller! In the end I became so desperate that I installed TreeSize Free. It quickly revealed that crash plan was taking up a huge amount of space. This revealed to be associated to the Code42 program — a program that the system was listing as taking 200MB. Well, uninstalling Code42 freed SIXTY PERCENT of the hard disk space, 140GB.
