hiberfil.sys Windows 8.1 Delete to Free Up SSD Space

Disable Hibernation on Windows 8.1 to Remove hiberfil.sys for More Disk Space

This article provides a tutorial on removing the Windows hibernation file to free up disk space when a small solid state disk (SSD) is used as the system drive. Please ensure you have a backup of any data and files you need to keep before changing system configurations. This article is for information only. System configurations can vary widely, therefore any changes made are at your own risk. If you’re confident with computers and understand the meaning of the hiberfil.sys file you can skip to the end of the article for the relevant command, which is to run powercfg -h off at the administrator’s command prompt, otherwise read on for a better understanding.

A SSD is more expensive than a hard disk drive, as a result small capacity SSDs (less than 128 GB) may be used to keep costs down. Windows 8.1 requires 20GB for installation, modern computing demands soon eats into the the remaining space. A system can be configured to use a small SSD for the Windows system and a large multi-terabyte  hard drive for data storage (see Move My Documents and Other Personal Folders). Despite this, or if a second drive is not an option, the SSD may fill up quickly with normal use. Once the SSD is full the computer or laptop will not function properly, may not boot up, or show error messages at boot time. The worst case scenario is data corruption and loss, or even disk failure, when applications cannot handle running with no disk space available. Continue reading
