You might have noticed that somewhere on your Windows 10 system there are a few GBs of unaccounted-for space. One of the places that this vanishing space is hiding is in the hiberfil.sys file. Besides being a big space hog, hiberfil.sys has another function for Windows 10 that you may not even use!
The Windows feature is called Hibernation. In the power settings and the mobility options for many PCs, going into Hibernation mode is a typical default setting. The general idea behind Hibernation mode is that it allows you to shut down your computer completely while saving your work/session so you can quickly turn your computer back on and pick up right where you left off. Now on a notebook, you can probably already see where this would be useful, particularly when you run into situations when you can’t afford to shut down but your battery is running low. Or perhaps the plane is about to land, and you need to shove your computer in your backpack quickly.

Try Sleep as an Alternative
If you’re using a desktop computer, however, hibernation becomes a much less useful tool for obvious reasons which could be why Microsoft includes a Sleep Mode which is tailored for desktop PCs. In sleep mode, your computer will go into low-power mode and essentially “pause” most essential services lượt thích turning off your hard drives, cranking your CPU way way down and shutting down fans. While it doesn’t save quite as much power as Hibernation, it does allows you to bring everything back up within seconds whereas Hibernate usually takes 30-60 seconds to start up and get going again.
Make sense? Agree we should get rid of Hibernation mode on that new/old desktop of yours? Ok, good. Let’s reclaim our previous hard drive space!
Note: By default, hiberfil.sys is a hidden and protected system file, so just to be able to see it we’ll need to tweak a few settings first. Let’s do that now.
