This tool allow to read/extract all images saved in Thumb.db file (created by MS Windows to cache your pictures). This application does not use any external libraries and you may run this tool on any computer without any additional setup/install (from USB flash or CD, for example). You may see the full system information (catalog structure with properties etc) and stored images in thumbnail. You may save (extract) as bitmap file the any stored picture or edit in editor (MS Paint, for example). MS Windows creates a file called "Thumbs.db" for folders that contain pictures. The Thumbs.db file caches a thumbnail version of the pictures in the folder, making it quicker to view the thumbnail images each time the folder is opened. Once a picture file has been deleted from the file system, the related thumbnail and associated metada remain stored in the Thumbs.db file. So, you may restore the image from cache (thumb.db) event if your real picture is deleted as file.
