What is the hibernation file and what purpose does it serve? What type of data can we expect to find in this file? Are hibernation files more prevalent on mobile devices? Please explain. Hibernate mode uses the hiberfil.sys file to store the current state (memory) of the PC on the hard drive and the file is used when Windows is turned back on. In Hibernate mode the PC power is down entirely, so you can even take the battery out, put it back in, and be right back where you were.  when hibernate is enabled it reserves some of your disk for its file -- the hiberfil. sys file -- which is allocated at 75 percent of your computer's installed RAM file to store the current state (memory) of the PC on the hard drive and the file is used when Windows is turned back on and  all the contents, and user work will remain as it is because contents of system’s RAM is stored on a hard disk by system. Since a mechanism was proposed for smartphones based on hibernation called Hibernation Mechanis...

Does Linux or Windows provide more evidence (artifacts) from a forensic analysis perspective? Please explain. According to (Imam, 2017), Linux holds many file systems of the ext family, including ext2, ext3, and ext4. Linux can provide an empirical evidence if the Linux-embedded machine is recovered from a crime scene. In this case, forensic investigators should analyze the following folders and directories. /etc    [%SystemRoot%/System32/config] This contains system configurations directory that holds separate configuration files for each application. /var/log This directory contains application logs and security logs. They are kept for 4-5 weeks. /home/$USER This directory holds user data and configuration information. /etc/passwd This directory has user account information.
