My 128GB Samsung 840 Pro C: drive has been taking up about 65GB of 119GB formatted space (55GB free space) for the longest time. Recently, it started showing only 38.3GB of free space. When I checked properties in Disk Management, it shows used space is 80.3GB and the free space is 38.7GB.
I downloaded WinDirStat and got the following results:

It's saying the used space of C: is only 69.5GB which is better but that still seems a bit high, although one heck of a lot better than 80.3GB.
Does anyone have any idea what is causing my C:drive to read so high all of a sudden? Btw, the 24.8GB for <Files> is normal. 24GB is the hyberfil.sys file (I have 32GB RAM) and I need Hibernation enabled for my UPS to use to shut down my computer without losing any work in the event of a power outage. The remaining 0.8GB is the pagefile.sys.
