Windows 10: SSD C:\ drive keeps filling up

I'm running Windows 10 and my C drive will randomly fill up suddenly. It will go from having 30+ GB free to only 6-10. I'll use disk cleanup but find less than a GB available to delete. Yet a few days later it'll go back to having 30+ GB free again. I installed TreeSize and am seeing that my System Volume folder has 40 GB. I'm enclosing a screenshot.Is that normal?I also have a hiberfil.sys and a pagefile.sys of about 9 GB each.Thanks in advance for your help.Mark

SSD storage keeps filling up on its own

Hi Ash,

There's a possibility that the files are just hidden. As an initial troubleshooting, we suggest following the steps below on how to display hidden files that's eating space of your SSD:

• On the Search bar, type folder, and then select
  Show hidden files and folders from the search results.
• Under Advanced settings, select Show hidden files, folders, and drives,
  and then select OK.

Keep us in the loop with the result.

 

SSD keeps filling up

Hey Carlos

So i just did reinstall my windows operating system, through windows it self. And before i did it, the problem wasn't there.

And by slowly filling up, i mean that over time the SSD (or c drive) is being filled up with files. But when i look in the c drive, nothing has changed. And yes i have done so i can see all the hidden folders. Its a 120gb SSD and the windows installation
fills up around 30-40gbit, so the rest is free space. It is slowly filling up the ~80gb up over 4-5 hours. Then when i restart the pc is back to the ~80gb of free space and slowly fills up again.
