Which Windows system file stores the RAM contents when the computer enters hibernation?

• A. Prefetch
• B. Hiberfil.sys
• C. System Restore Points
• D. Thumbs.db

Answer: (A)

When a Windows machine hibernates, it saves the current RAM contents to disk so you can power off completely and resume exactly where you left off. This memory dump is stored in a system file called hiberfil.sys on the system drive, sized roughly to match the amount of RAM installed. On resume, Windows reads from this file back into RAM to restore the previous state. The other options serve different purposes: Prefetch speeds up program startups by caching data, System Restore Points capture a snapshot of system state (not memory), and Thumbs.db caches image thumbnails. None of them store the live RAM for hibernation like hiberfil.sys does.
