Many of you may have noticed the presence of the hiberfil.sys file on Windows 10, 8, 7. It is located in local disk drive C and takes up GBs HDD space on your PC. More often than not, this hibernation file appears along with the pagefile.sys file in C drive.

On a simple note, this hiberfil.sys file comes into being for the purpose of enabling you to enter the hibernation mode on your PC.

Specifically, as you all know, there are mainly four power options on Windows systems, namely, sleep, hibernate, shut down and restart. Normally, people tend to go into sleep or hibernate mode when they feel like waking up the PC quickly. Compared with the sleep mode, the hibernate mode can conserve more power as it will write the information out to the drive in the form of hiberfil.sys file.

For instance, if your PC memory uses 2GB, then this hibernation file may take up 2GB or more to work smoothly.
