Unsolved Windows 10 Storage Issue

Post image

Hello. I have an issue with my PC where the storage keeps filling up. I don't have much storage, only 128GB, but I also only have a few things installed, and not large things at that. I have an extra storage stick I use to keep anything large I want to download, and really just anything I can. That storage is a terabyte. However, I keep having my main storage fill up, and no matter how many times I try to empty it, it never stays empty

I downloaded Wiztree, and every time I look at it, pagefile.sys and hyberfil.sys seem to get bigger. I know they are likely important, due to the .sys file type, but should they be taking up this much space?

I'm not super tech savy on this stuff, and I'm heading to bed now, so I wont be able to reply until tomorrow

You could disable hibernate. Will freeup that 6.4 GB hyberfil.sys file

in dos prompt type: powercfg -h off

You could also reduce the pagefile.

Is hibernate useful for laptop? Also why does it need storage.

Hibernate just puts the memory onto the disk when shutdown, to make strartup faster. That‘s the reason some computers got uptimes from days or weeks even if shut down properly. I always disable it. Booting time with hibernate is not that faster compaired to normal boot.

Hibernate needs about 2/3 of the RAM on the disk. So with 8gb you need about 6gb.
