The function of hiberfil.sys file:

This file is a memory image file automatically generated by the system after the hibernation function is turned on, so that we can start the program quickly after we wake up the computer.

1. This paper introduces the difference between dormant HIBERNATE and sleep SLEEP in windows system. We often use sleep SLEEP function, that is, after a certain period of time, the computer enters a state of low power consumption, the working attitude is kept in memory, and the original state can be restored in 1-2 seconds after recovery. This function is practical and the most commonly used. Hibernation is to write the working status, that is, all memory information, to the hard disk, if there is 2-4G memory, that is, to write 2-4G files to the hard disk before shutting down the computer, and to restore the original interface by reading 2-4G files into memory. However, reading and writing large files takes a lot of time, which is no less than the normal boot, so now the hibernation function is not practical (for more than 1G of memory). Dormancy is not a sleep function! The average notebook user may take advantage of hibernation is to write all the data in memory to the hard disk, then shut down the system, and then write the data back to memory the next time you boot, but it will take some time. The advantage of this is that your ongoing work will be saved and will not disappear even after a power outage, which is why it is often said that you do not have to shut down for several months.

Most people don't use this feature very often, but we pay the same amount of disk space as memory for it, thanks to it! In fact, we can start it when we need it, and usually turn it off directly. From here, we can see that the sleep function is much better than hibernation, and the current state of the computer is saved, and the boot speed is very fast, so under normal circumstances, you can delete dormant files, and the recovery is also very simple, which will be introduced below.

two。 Delete the dormant file:

Run CMD as an administrator and issue the following command:

POWERCFG-H OFF

That is, automatically delete the file, which is as large as memory. For example, the file with 2 GB of memory is also 2 G. You can see the change of C disk space before and after processing. Restore the hibernation function, that is, run CMD as an administrator and issue the following command: POWERCFG-H on also has a fool-like convenient way to turn hibernation on and off:

Copy the following code, paste it into notepad, and then save the file as turn off hibernation .bat

@ powercfg-h off copy the following code, paste it into notepad, and then save the file as hibernating .bat @ powercfg-h on.
