How to read Windows hibernation file (hiberfil.sys) to extract data?



Hibernation is a computer technology used to save the state of a computer system. It is used to save system resources and reduce overall power consumption. When a computer is put into hibernation mode, the system is put into a low-power state, and all of the data stored in memory is stored in a file on the hard drive called the hibernation file, or hiberfil.sys. The data stored in the hibernation file can be used as a backup in the event of a system crash or power outage.

In some cases, an IT admin may need to read the hibernation file to extract data stored on the computer. Extracting data from the hibernation file can be a useful tool for troubleshooting computer problems or recovering lost data. The data stored in the hibernation file can include information about user accounts, system settings, and files that were open when the computer was put into hibernation.

To read the hibernation file, an IT admin must first locate it on the hard drive. The hibernation file is usually located in the root directory of the system drive. It is a hidden file and must be enabled to be seen. To enable the file, open the file explorer, click on view, and select “show hidden items”. Once the file is visible, double-click on it to open it. Once the file is open, the IT admin can use a text editor to view the contents of the file.

The contents of the hibernation file are written in a binary format, which is not easily readable. To make the contents more readable, an IT admin can use a utility program such as Hibernation File Reader to open and read the file. Hibernation File Reader is a free tool that allows users to view the contents of the hibernation file in a more readable format.

Once the contents of the hibernation file have been read, the IT admin can extract data from the file. Data such as user accounts, system settings, and files that were open when the computer was put into hibernation can be extracted from the file. The exact data that can be extracted depends on the operating system used by the computer.

In some cases, the data stored in the hibernation file may become corrupted. If this happens, the IT admin may need to use a data recovery utility to recover the data. Data recovery utilities are designed to scan the hard drive for corrupted files and attempt to restore them.

In summary, an IT admin can read the hibernation file to extract data stored on the computer. The data stored in the file can include information about user accounts, system settings, and files that were open when the computer was put into hibernation. To read the file, the IT admin must first locate it on the hard drive and enable it to be visible. Once the file is visible, a text editor or the Hibernation File Reader can be used to view the contents of the file. The IT admin can then extract data from the file. If the data stored in the hibernation file is corrupted, a data recovery utility may be needed to recover the data.
