Win8 sleep file (HIBERFIL.SYS) is too large to account for how to delete memory?

Our computer usually uses the sleep function, that is, the computer enters the low-power state after a certain period of time, and the working attitude is stored in the memory. When the recovery is 1-2 seconds, it can be restored to the original working state. This feature is very useful and is the most commonly used.

And hibernation is to write all the memory information into the hard disk, taking 4G memory as an example, that is, to write 4G files to the hard disk, and then shut down. To restore the original working interface, you need to read the 4G file to the memory. The reading and writing of 4G files takes a lot of time, which is no less than normal booting, so the hibernation function is not practical now (for 1G or more memory, 512MB or less of small memory still has a certain effect). The hibernate HIBERFIL.SYS file is used to save memory state during sleep. Will occupy the space equivalent to the memory capacity of the C drive (for example, 4G memory, this file is also 4G), so it can be deleted without affecting everyone's use. It will also greatly reduce the occupation of the C disk space.

Like the screenshot below, this file takes up more than 6G of space on this machine.

1. Right-click on the blank space in the Start menu and click on “All Apps” in the lower right corner. 2. Find the “Command Prompt” and right click on ““ Run as administrator”

3. At the command prompt, type “powercfg -h 0ff”

4. Let's go back to the system disk root directory and find the hibernation file. It was automatically cleared.

Note: You must run the "Command Prompt" as an administrator, otherwise you will be prompted to find the command.
