What are the hiberfil.sys and pagefile.sys files and whether they can be deleted? for this question, this article introduces the corresponding analysis and solutions in detail, hoping to help more partners who want to solve this problem to find a more simple and easy way.

On the system disk, there are two system files with the suffix .sys: hiberfil.sys and pagefile.sys.

Hiberfil.sys is the backup file left behind after the computer uses the hibernation feature. We know that the dormant state of the computer can be guaranteed to keep the memory files in the event of a power outage. This hibernation feature benefits from hiberfil.sys files. When the computer is dormant, the memory file will be saved to the hiberfil.sys file on the hard disk, and then when the computer is awakened again, the read information will be restored to memory, just like the state before hibernation.

Since this file is used to back up memory information, its size is generally the same as the size of computer memory, but the footprint of this file can be reduced by setting and using compression technology. The setting method is as follows: in the command prompt cmd window, enter the command: powercfg-H size 50, and the dormant backup file will be compressed to 50% of memory.

If you don't want to use hibernation, you can delete this file completely, but turn off hibernation first, otherwise even if you delete this file, it will still appear the next time you use hibernation. The way to turn off the sleep function is as follows: in the command prompt cmd window, enter the command: powercfg-H off.

Pagefile.sys is a virtual memory page file created during installation, and the size of this file is set by the virtual memory of the system. If the system disk space is insufficient, you can manually set the size of the virtual memory page file as follows:

Right-click "computer"-"Properties", select "Advanced system Settings"-"Settings"-"Advanced" changes, and then in the following pop-up box:

Do not check "automatically manage the paging file size of all drives", that is, you can set the paging file size of each drive, you can choose the "custom size" way to set the initial size and maximum value. This optimizes the size of the in-memory page file.

This is the answer to the question about what the hiberfil.sys and pagefile.sys files are and whether they can be deleted. I hope the above content can be of some help to you.
