Win7 how to turn off hibernation

Everyone installed Win7 system is not closed after the sleep function, if not turned off, will occupy the space of C disk, presumably this problem everyone knows, I installed the WIN7 system, the first thing is to turn off hibernation.

    I used the method is to turn on power management, and then when the computer using the external power supply and battery-only state, the sleep time to never, then determine, This turns off hibernation, but does it really turn off hibernation?

    If you close a sleeping friend by using the above method, you can open the C disk, then open the folder option, select View, remove the hook from the hidden protected operating system file, and then make sure to look at the extra large push hidden file, Whether there is a file called Hiberfil.sys, this file is a boring file, even if you use the above method to turn off the hibernation function, the file still exists.

    if not, then I don't say ah, oh, if the file directly deleted, this is not a scientific approach, I tried at that time, System prompts can not delete, but I did not use 360 of the file grinder, interested friends can try, Oh, but I still feel that should be deleted correctly, not forced to delete.

    Now all I want to say is how to completely turn off hibernation, including this folder by:

    Click Start--All Programs--attachments--command Prompt--then right-click--Run as administrator, remember to run as an administrator, or not, and then enter powercfg-h off in the Open Command Prompt window and return.

    This completely shuts down hibernation, and when you look at the space in C disk, is it a part of it?

    If you want to turn on hibernation again, use this method to open a command prompt window or to run as an administratorLine, then enter powercfg-h on, so that the hibernation is turned on again, and that file appears again.
