Delete Hiberfil.sys To Save Some Disk Space

» I want to delete the hiberfil.sys to save some disk space. The reason I am trying to do this is becuase, the hybrnation feature is already deselected in GUI. But this file is taking up alost 2 GB space. I tried running the command in CMD and ran As Administrator, powercfg -h off. But I get a message that I do not have permission to enable or disable Hiberntion. So please suggest if I can delete this in my Windows 7 and in future if I want will I be able to use hibernation?

» Hibernate mode uses the hiberfil.sys file to store the current state (memory) of the PC, and since it's managed by Windows, you can't delete the file. If you routinely use Hibernation mode, this trick isn't for you. If you never use Hibernate mode on your desktop or laptop, this trick will free up 4-6GB of disk space on your system disk.

Windows has two power management modes that you can choose from: one is Sleep Mode, which keeps the PC running in a low power state so you can almost instantly get back to what you were working on. The other is Hibernate mode, which completely writes the memory out to the hard drive, and then powers the PC down entirely, so you can even take the battery out, put it back in, start back up, and be right back where you were.

Hiberfil.sys file acts as one of the component that is used to ensure the smooth running of the computer. It is the original file of hiberfil.sys error which can severely destroyed your crucial system files. Various reasons that can cause hiberfil.sys error, containing corrupt or incompatible xlive.dll file, missing xlive.dll file, dynamic link files damage, incorrect BIOS setting and malware issue.

And it is widely know that viruses(Rogue:Win32/FakeCog) are able to attack and rename or remove any file on your hard disk. When a necessary hiberfil.sys file was mis-deleted due to virus infection, the hiberfil.sys files won't be working correctly. To fix hiberfil.sys errors as well as maintain computer speed, you'd better immediately run your antivirus antispyware program to completely scan and remove all PC threats. By the way, it is best that you can let your computer protection program always in the background to realtime block & remove any potential threats.

  2. MANUEL GONZALES replied on March 9, 2013: » One critical detail is missing: Right-click Command Prompt and select "Run as administrator." Then the command will work.

    So, the complete instructions are as follows: Click Start > All Programs > Accessories > Right-click Command Prompt > Select Run as administrator > Grant permission to change system settings > In this privileged command prompt window, enter: powercfg -h off

    Poof! hiberfil.sys is gone -- instantly!

    It only took a few seconds to delete the file from the file browser window there. :) It shows up as for example, 21 GB Filesystem with a hard disk icon, so you don't even have to search for /media/sda2 or anything Linuxy like that. :D
