Hello good people of bleepingcomputer, I've just registered to this forum for a particual problem that I have. Now I'll bore you with the details:
I am currently using a Sandisk 480GB SSD HDD on my laptop (which I know makes 457860MB). It is divided into 2 partitions, C being the main drive and F for data etc.
I have come to realize that my C drive shrinks in size for no reason at all. And when I checked the data used and the actual file sizes I saw a discrepancy:
Windows's own Disk Management utility reports that out of 214,29GB allocated I have 63,57GB free space, which is the same stat I see whichever program I look at.

The problem is according to this data, there should be 214,290 - 63,57 = 150,72GB used disc space on C, but it's not the case and I have been trying to confirm this any way I can.
First of all I tried to use WindirStat to show me what uses what and what I came up with is that with everything there, it's in total 125,5GB used.

Now I realize this might be redundand and I might be missing some system files tha Win fileystem doesn't let me see, but I would like to include 2 more screenshots of other programs reporting on used space:
The only software that was able to tell me that yes, C: was indeed using 150GB, is HDD Sentinel that I just happened to have installed.

Note: After finding out that my HDD space was decreasing I have tried to clean it up via a couple of methods, so all the screenshot here are after the cleanup:
1. Ccleaner 2. Windows Disk Cleanup utility (including removing System Restore and Shadow Copies) both of which worked, and pulled my usable space from 50GB to 63,5GB.
Although they improved the situation, I still have some 25GB inexplicably missing. I hope someone has an explanation to this thing because it's seriously bugging me.
