What is this 'Thumbs.db'?

Question

I can't see these file on Windows Explorer but when I scan the folder, there are lots of them taking lots of spaces on my hard disk. How can I deleted these files? If I delete these files, will it be harmful to my PC?

Answer 1

The thumbs.db is a file that is created so that when you view the folders on your computer, it shows an image for each folder, a picture, instead of just an icon.

You can delete them if you want, but they will be recreated next time you view that folder.

Answer 2

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.

The Thumbs.db file is often viewable when the "Show Hidden Files" option is turned on in Windows. To activate this setting, first open a folder in Windows. Then choose "Folder Options" from the Tools menu.

Answer 3

These file are little databases windows uses to store preloaded image previews you are fine deleting them but when you open a folder with photo previewing on it will just make a new one. They will not hurt your computer and they are normal.
