Hiberfil.sys – what is it and how to remove it

febrero 1, 2020

You may be able to discover unusually large files on the computer, named Hiberfil.sys. These files can actually consume space and limit the amount of storage that can be used for storing or using other important files. There is nothing to worry about however, this file is not a sign of malicious infections or anything like that. It is simply a way for the Windows system to hibernate and return to use without a hitch or loss of data. It is therefore very useful if the user is intermittent and sometimes leaves the computer unattended or inoperative.

The main player for file creation is a power saving function. By allowing the computer to hibernate when not in use, all Windows systems become inactive, which reduces power consumption and reduces battery life and real energy costs. This is specifically for long periods of inactivity, unlike the sleep function. The 'hibernation' option will give the user a quick start and resume time, which can be very handy.

When "Hibernate" mode is selected, the computer quickly writes all status information to the hard drive to allow the computer to return to the status when requested. The size of the Hiberfil.sys file therefore depends on the services used at the time of the hibernate command.

How to remove Hiberfil.sys?

since the file has a specific use, not all users will use it. To free up more space, the file can be deleted when the user is not interested in using the hibernation function. However, the process is not as obvious as it sounds and, more importantly, it should be done safely, because Windows is deliberately placing it there. It is also different on Windows systems.

The file can be safely deleted by all users who do not use the "Hibernate" option on Windows Vista and Windows 7-10 operating systems by means of a few commands, which essentially constitute a deactivation of the file. Sleep mode.

  • First display the initial search bar and search for Command Prompt. Set the options by right-clicking on them and choose to run the program as a quad administrator.
  • A popup window will ask you if you agree to modify the computer with the application. Accept and continue.
  • Once you accept, a window terminal will appear. Type the command '' powercfg -h off '' because it includes spaces, then press the return key.
  • Close the window and return to the location where the file was found. If the process has been executed correctly, the file should be deleted at this stage, since deactivating the "Hibernate" option automatically deletes the data storage file for this mode.
  • If, at some point, the user wishes to use the "Hibernate" option, simply repeat the process, but this time, type the command "" powercfg -h on "instead and you're ready to go!

For Windows XP, the file can be disabled with a slightly different and slightly simpler process.

  • In the control panel, select the power options and open the "Hibernate" tab.
  • Once opened, there will be options to activate or deactivate it. Select deactivate and close the window.
  • Once deactivated, you must manually delete the file in its source folder and you are also ready to go!

Getting rid of the file can save memory, however, the hibernate option is always better than full shutdown due to the reduced boot time and because it automatically saves the work progress in case user forgets to do this, which often happens. for most users. Once turned off, you will notice that the Hibernate option automatically disappears from the power options, which is a security feature to avoid selecting it by mistake and causing data loss or corruption problems.
