Which Windows file stores thumbnail previews of images and documents?

Which Windows file stores thumbnail previews of images and documents?

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

Answer: (C)

Thumbnails are cached to speed up folder views, so Windows keeps a small database of preview images right inside the folder. The file that stores these thumbnail previews is Thumbs.db. It’s a hidden file created in each folder that contains images or documents, and it holds the generated thumbnail images for quick display when you open that folder. To contrast, prefetch is about speeding up program launches by caching data about executables, system restore points are backups to revert the system state, and hiberfil.sys is the memory image used when the computer enters hibernation. None of those store image or document thumbnails.
