Thumbs.db is a hidden system file that is automatically created by Windows Explorer (File Explorer) in all folders containing image and video files. File Explorer creates thumbnails of the images in the directory and saves them to the thumbs.db file (a COM structured storage).

By using the cache, the time it takes to load and display thumbnail files in File Explorer is greatly reduced.
