When you have images, photos or movies in a folder, Windows recognizes the files and tries to show you them in "thumbnail" view, or maybe even in the "filmstrip" view. When it shows you the thumbnails, it creates a file called thumbs.db which contains information about those thumbnails so that the pictures can be displayed quickly the next time you view that folder.

If you hate those thumbs.db files, you can delete them without causing any harm to your computer. Here's how to stop Windows from ever creating those thumbs.db files ever again: 

• Click on the Start button
• Choose Control Panel
• Choose Folder Options
• Click the View tab
• Check the box that says Do Not Cache Thumbnails
• Click OK
