Why Delete Hiberfil.sys?

When your computer goes into Hibernate mode, Windows stores your RAM data on the hard drive. This allows it to save the system state without power usage and boot right back up to where you were. This takes up a great deal of drive space. When you delete hiberfil.sys from your computer, you will completely disable Hibernate and make this space available.

Re-Enabling Hibernate

If you change your mind, you can easily enable Hibernate again. Simply open the Command Prompt once more. Type powercfg.exe /hibernate on, press Enter and close the Command Prompt window. In Windows XP, simply open the Power Options Properties dialog box and select Enable Hibernation.
