Windows creates the hiberfil.sys file automatically when you turn on the
Hibernate feature; the only way to delete the file is to turn off Hibernate.
To do this, open a Command Prompt window in administrator mode (see
???The solicitude of Sleep,??? earlier in this chapter, for details) and type this
command at the prompt:
powercfg /hibernate off
Then press Enter. If the command returns you to the prompt with no message,
the change was successful, and hiberfil.sys should be gone.
If hiberfil.sys is still there, hibernation may??™ve already been turned off, and the
file may be left over from an older version of Windows. Another way to delete
the file is to use the Disk Cleanup tool (cleanmgr.exe); just select the drive
containing the file, place a checkmark next to Hibernation File Cleaner in the
Files to delete list, and click OK.

The options and choices vary depending on your PC??™s capabilities, but in
most cases, you should see at least Power button action, which refers to
your PC??™s main power switch, and Start menu power button, which refers
to the red button next to the Search box in your Start menu. You may also
see Sleep button action if your keyboard or PC has a formal Sleep button
(which looks like a crescent moon), and Lid close action if you??™re using a
laptop.
