Mystery disk space loss

[Racker2]

A few days ago my ssd showed 90+ GB of remaining space. Yesterday, when I checked the disk space, there was only 60+ GB remaining. I have not done any downloading of any significance lately. My desktop has 1 terabyte of storage divided in 2 disks, 500 GBs each. The disk showing the loss is where I have stored Steam and my racing games. Any ideas?
BTW, this has happened before. I have Windows 10

TreeSize Free is a free disk space manager for Windows. The software shows you the sizes of folders including all subfolders.

Install it, run it. Find out where you have folders that have way too much content. Delete.
You might also find fun stuff like a hugenormous google chrome cache, old nVidia driver-backups, game recordings you didnt mean to record etc.

Thanks, I tried it and found an old Windows backup file worth 30 GB. More to come!

In folder options untick "Hide protected operating system files "
Then go to each partition and click on all Recycle bins you may find
space if there is multiple recycle bins on 1 partition
You can safety delete all recycle bins apart from the latest

P.S. To change back tick the same box 2 times ( for user and all users )

I use Spacesniffer when stuff like this happens, just make sure to run it as Admin.
Oh, and it's absolutely free.
