Issue: How to remove hiberfil.sys file from Windows?

Hiberfil.sys file takes up loads of RAM memory, so I would like to uninstall it. It’s a long time since I did not use hibernation mode, so I assume that this file is no longer needed. Could you please help?

Solved Answer

Hiberfil.sys is a temporary file that is created by Windows OS for saving the memory in hard drive. This is necessary if the PC/laptop user wants to put the system into the hibernation mode. Hibernation mode is one of the two power management modes available on all Windows OS versions. Typically, the computer or laptop is put in a low power state by enabling Sleep Mode.

For this purpose, the PC/laptop owner sets a required Power Plan, which then automatically puts the system into Sleep Mode when it stays idle for 5 minutes or more. However, all Windows versions,[1] including Vista, XP, 7, 8.1, 8, and 10 allow putting the system in Hibernation Mode, which completely turns off the machine thus using zero recourse.[2]

Nevertheless, just like with Sleep Mode, rebooting the system after hibernation will restore the exact state of the system as it was before enabling hibernation. The problem is that to enable this state Microsoft creates the hiberfil.sys file, which is stored in the C: drive and uses 75 percent of the RAM[3] by default.

Such huge memory occupation may reduce the system’s performance significantly, especially if you are using an old computer with low RAM storage (e.g. 160 GB). If you have never tried enabling Hibernation Mode and do not plan to do so, it would be wise to remove hiberfil.sys file completely.
