Question SSD is running low on storage without doing anything?

[Kris_the_midge]

So the other day I launched Rainbow 6 to play with friends and I get a notification that my SSD is low and I mean I have 700 Mb left! This is awkward because a couple of days ago I checked and I had at least 7 gigs of storage. I had games stored on my SSD for some reason namely Fortnite which had been rusting there for about a year. I deleted Fortnite and then I got 64 gigs of storage back.

I then ran a Malwarebytes scan (I have premium for 14 days) and it found nothing (Malwarebytes does a scan twice every day). The scan came clean and all the past scans were also clean so that's that for now. I then quit Malwarebytes and continued playing R6 with my friends. After one match I noticed I had 100mb less than before.

I quit the game to go on google to search for some people with my problem or at least a similar one and then I come back and see that the 100 MB I lost somehow were back. I have no idea how this happened. After that I did a full virus scan with avast (don't know if it scans for all malware) and after about 20-30 minutes it came clean.

I still had some speculations so I shut down my PC and removed the ethernet cable and now I am here. Anyone know how to solve this issue? Anybody else encountered it? and finally what's the chance its a worm?

See if you have the CBS log file issue. It is not common but I've seen it several times recently in Windows 10 no less.

Thanks for your reply!
I have used TreeSize to check and most I have a little problem. Treesize says I have used 164 gigs of my C: drive and when I go on to settings and storage and its says I used 153 gigs of storage. While using TreeSize it told me that most if not all is used from steam games and windows. I checked the folder you told me and found that the folder contains less than 1 GB of storage. I understood what was taking up most of the storage but I still don't know why my storage goes up and down while playing games or just being on google. I lose about 200 megabytes. Sometimes I also magically regain storage as well. Why does this happen? Can it be malware?

Since it's steam, I'm suspecting temporary game saves in your user folder. When you exit it the game it should delete the temps and leave you with the primary.

Are you recording you gameplay?

You might be able to gain several GB of space by custom setting your recycle bin's properties for the drive in question down to just 2000-4000 MB or so...; it's a shame to reserve sometimes 5-10% of it's space for never used functions.
