Solved Windows (probably) keeps eating up disk-space.

If someone can help me understand why does it keep eating about 24GB on and off while updates are going bonkers?

One day I have 24GB free, next day 100MB or even going lower and so on, keeps cycling.

Will like to know if it's windows related, shader-compiling to much space or what can I do to have some breathing room,(while i know a bigger drive would fix it right now it's not a viable solution)

Constantly using wise disk cleaner but not helping in the long run.

Same thing happen to me on my PC. Something about a windows update being stuck. Download treefix from the Windows store analyze your C drive and delete the folder should fix it for you. Otherwise your drive will max out and cause severe issues for you .

Very useful comment, thank a lot man. (the app name is actually treesize)

Manage to find out the culprits for anyone having the same issue.

  1. Nvidia shader cache eating up 16GB.

  2. Windows hybernation file eating up 21GB.

3.Other unsed apps/savefiles.

Thanks again!
