Really, the but reason to disable hibernation and delete hiberfil.sys is to relieve disk space. If you have a small SSD with only a few gigabytes free, disabling hibernation makes sense if you never utilize it. You can try other methods to free up space in Windows before getting rid of hibernation, though.

With larger drives (500GB or more than), using i-5 percent of your deejay infinite for a useful feature isn't every bit big if deal.

Unless you leave your PC on all the time, you should requite hibernation a endeavor to see if it works for yous earlier disabling it.

For nearly people, we recommend giving hibernation a try and seeing if information technology saves you some time. If you end upward never using it and need the actress disk space, get alee and disable it---Fast Startup doesn't provide a massive do good anyway.

While it's safe to remove the hibernation file in the fashion we described above, there are other default Windows files you should never bear upon.
